Common_Sim_Bus_Interfaces
{{>toc}}
All GUNNS link classes have many variables, and Sim Bus can read & write to almost all of them. Which ones do you use? The links are designed to interface with other classes in specific ways, but we sometimes find other ways to interface them that the designers didn’t foresee. It’s not always obvious which terms to interface via the Sim Bus. This page is an attempt to detail the most important interfaces, but we can’t detail them all. So in addition to this guide, here are some tips for determining the link variables to use on your own:
- Refer to the link class declarations in the source code (*.hh files):
- All links source code is either in gunns/core/ or gunns/aspects/.
- Sometimes the Trick comments in the variable declaration will indicate that it is meant as a Sim Bus input or output.
- Aspect diagrams will typically not spell out the actual variable names to interface, but will give a clue as to the type of parameter you are looking for, such as a temperature or a flow rate, etc., which you can then look for in the link class’ attributes.
- See the big table below.
The main purpose of the ICD.txt file examples below is to show you which link variables to use for specific interfaces. Pay attention to the suffix variables in the SIM_VAR_NAME column, i.e. thermal.capacitor. mTemperature — these are the variables you are looking for. The other columns just give example names.
This is a common interface where a fluid aspect calculates a heat flux transferred from the fluid to the wall based on a wall temperature from the thermal aspect. The fluid aspect sends a heat flux Q to the thermal aspect, and receives a wall temperature T from the same thermal aspect. The thermal aspect is usually a GunnsThermalCapacitor link, and the fluid aspect is usually a GunnsFluidTank or most conductor link that do wall convection, such as a GunnsFluidValve, GunnsFluidFan, GunnsFluidPipe, etc.
The thermal capacitor’s mExternalHeatFlux term is actually an array to receive up to 15 heat fluxes from various sources. You would typically send one heat flux to array position 0, the next to 1, and so on as needed.
There is an aspect diagram of this configuration in the GunnsDraw link help page for the GunnsFluidTank. We are talking about the first pattern shown for that link, where the fluid tank calculates Q. Here is what the ICD.txt file would contain for an example case:
PUI SYS BUS SUBSYS VAR_NAME ACTION RATE SIM_OBJECT SIM_VAR_NAME TYPE UNITS COMMENTS # Exchange wall temperature and heat flux between a thermal capacitor & fluid tank: # # Wall temperature from thermal to fluid aspect: xxxx sys bus subsys wallT WRITE rate SimObject simObject thermal.capacitor.mTemperature double (K) Wall temperature xxxx sys bus subsys wallT READ rate SimObject simObject fluid.tank.mShellTemperature double (K) Wall temperature # Wall heat flux from fluid to thermal aspect: xxxx sys bus subsys wallQ WRITE rate SimObject simObject fluid.tank.mHeatFluxToShell double (W) Wall heat flux xxxx sys bus subsys wallQ READ rate SimObject simObject thermal.capacitor.mExternalHeatFlux[0] double (W) Wall heat flux
For the fluid conductors GunnsFluidPipe, GunnsFluidValve, GunnsGasFan and their derived classes, the pattern is the same except for different variable names in the fluid link:
PUI SYS BUS SUBSYS VAR_NAME ACTION RATE SIM_OBJECT SIM_VAR_NAME TYPE UNITS COMMENTS # Exchange wall temperature and heat flux between a thermal capacitor & fluid conductor: # # Wall temperature from thermal to fluid aspect: xxxx sys bus subsys wallT WRITE rate SimObject simObject thermal.capacitor.mTemperature double (K) Wall temperature xxxx sys bus subsys wallT READ rate SimObject simObject fluid.conductor.mWallTemperature double (K) Wall temperature # Wall heat flux from fluid to thermal aspect: xxxx sys bus subsys wallQ WRITE rate SimObject simObject fluid.conductor.mWallHeatFlux double (W) Wall heat flux xxxx sys bus subsys wallQ READ rate SimObject simObject thermal.capacitor.mExternalHeatFlux[0] double (W) Wall heat flux
The GunnsFluidHeatExchanger link can have 1 or more segments, and each can have its own Q/T exchange with a separate thermal asepct. See Example 3 in the “Typical HX Connections” diagram in the above link. A 4-segment counter-flow configuration is typical of this link, and we show the ICD for this configuration below. There are 8 separate Q/T exhanges created here, 4 for each of the 2 fluid loops. Like the tanks and other conductors, each segment has the same Sim Bus interface pattern, just with different target variables in the fluid link:
PUI SYS BUS SUBSYS VAR_NAME ACTION RATE SIM_OBJECT SIM_VAR_NAME TYPE UNITS COMMENTS # Exchange wall temperature and heat flux between thermal aspect and 2 fluid loops for a 4-segment counter-flow heat exchanger: # # Temperature and heat fluxes for segment 0: xxxx sys bus subsys seg0T WRITE rate SimObject simObject thermal.capacitorHxSeg0.mTemperature double (K) Segment temperature xxxx sys bus subsys seg0T READ rate SimObject simObject fluidCold.heatExchanger.mSegTemperature[0] double (K) Segment temperature xxxx sys bus subsys seg0T READ rate SimObject simObject fluidHot.heatExchanger.mSegTemperature[3] double (K) Segment temperature xxxx sys bus subsys seg0ColdQ WRITE rate SimObject simObject fluidCold.heatExchanger.mSegEnergyGain[0] double (W) Segment heat flux xxxx sys bus subsys seg0ColdQ READ rate SimObject simObject thermal.capacitorHxSeg0.mExternalHeatFlux[0] double (W) Segment heat flux xxxx sys bus subsys seg0HotQ WRITE rate SimObject simObject fluidHot.heatExchanger.mSegEnergyGain[3] double (W) Segment heat flux xxxx sys bus subsys seg0HotQ READ rate SimObject simObject thermal.capacitorHxSeg0.mExternalHeatFlux[1] double (W) Segment heat flux # Temperature and heat fluxes for segment 1: xxxx sys bus subsys seg1T WRITE rate SimObject simObject thermal.capacitorHxSeg1.mTemperature double (K) Segment temperature xxxx sys bus subsys seg1T READ rate SimObject simObject fluidCold.heatExchanger.mSegTemperature[1] double (K) Segment temperature xxxx sys bus subsys seg1T READ rate SimObject simObject fluidHot.heatExchanger.mSegTemperature[2] double (K) Segment temperature xxxx sys bus subsys seg1ColdQ WRITE rate SimObject simObject fluidCold.heatExchanger.mSegEnergyGain[1] double (W) Segment heat flux xxxx sys bus subsys seg1ColdQ READ rate SimObject simObject thermal.capacitorHxSeg1.mExternalHeatFlux[0] double (W) Segment heat flux xxxx sys bus subsys seg1HotQ WRITE rate SimObject simObject fluidHot.heatExchanger.mSegEnergyGain[2] double (W) Segment heat flux xxxx sys bus subsys seg1HotQ READ rate SimObject simObject thermal.capacitorHxSeg1.mExternalHeatFlux[1] double (W) Segment heat flux # Temperature and heat fluxes for segment 2: xxxx sys bus subsys seg2T WRITE rate SimObject simObject thermal.capacitorHxSeg2.mTemperature double (K) Segment temperature xxxx sys bus subsys seg2T READ rate SimObject simObject fluidCold.heatExchanger.mSegTemperature[2] double (K) Segment temperature xxxx sys bus subsys seg2T READ rate SimObject simObject fluidHot.heatExchanger.mSegTemperature[1] double (K) Segment temperature xxxx sys bus subsys seg2ColdQ WRITE rate SimObject simObject fluidCold.heatExchanger.mSegEnergyGain[2] double (W) Segment heat flux xxxx sys bus subsys seg2ColdQ READ rate SimObject simObject thermal.capacitorHxSeg2.mExternalHeatFlux[0] double (W) Segment heat flux xxxx sys bus subsys seg2HotQ WRITE rate SimObject simObject fluidHot.heatExchanger.mSegEnergyGain[1] double (W) Segment heat flux xxxx sys bus subsys seg2HotQ READ rate SimObject simObject thermal.capacitorHxSeg2.mExternalHeatFlux[1] double (W) Segment heat flux # Temperature and heat fluxes for segment 3: xxxx sys bus subsys seg3T WRITE rate SimObject simObject thermal.capacitorHxSeg3.mTemperature double (K) Segment temperature xxxx sys bus subsys seg3T READ rate SimObject simObject fluidCold.heatExchanger.mSegTemperature[3] double (K) Segment temperature xxxx sys bus subsys seg3T READ rate SimObject simObject fluidHot.heatExchanger.mSegTemperature[0] double (K) Segment temperature xxxx sys bus subsys seg3ColdQ WRITE rate SimObject simObject fluidCold.heatExchanger.mSegEnergyGain[3] double (W) Segment heat flux xxxx sys bus subsys seg3ColdQ READ rate SimObject simObject thermal.capacitorHxSeg3.mExternalHeatFlux[0] double (W) Segment heat flux xxxx sys bus subsys seg3HotQ WRITE rate SimObject simObject fluidHot.heatExchanger.mSegEnergyGain[0] double (W) Segment heat flux xxxx sys bus subsys seg3HotQ READ rate SimObject simObject thermal.capacitorHxSeg3.mExternalHeatFlux[1] double (W) Segment heat flux
Note how the mapping of reads & writes between the segments creates the counter-flow effect. By convention, the thermal aspect segment numbering matches the order of the “cold” fluid loop, and the “hot” fluid loop reverses its segment order to create the counter-flow effect, like so:
(cold fluid seg 0) <--T------Q--> (thermal seg 0) <--Q------T--> (hot fluid seg 3) (cold fluid seg 1) <--T------Q--> (thermal seg 1) <--Q------T--> (hot fluid seg 2) (cold fluid seg 2) <--T------Q--> (thermal seg 2) <--Q------T--> (hot fluid seg 1) (cold fluid seg 3) <--T------Q--> (thermal seg 3) <--Q------T--> (hot fluid seg 0)
GunnsBasicExternalDemand and GunnsBasicExternalSupply are typically paired across the Sim Bus to create a flow interface between two Basic (thermal or electrical) networks. See the aspect diagram in the above links.
A node potential value is sent from the Supply link to the Demand link, and a demand flux value is sent back, like so:
PUI SYS BUS SUBSYS VAR_NAME ACTION RATE SIM_OBJECT SIM_VAR_NAME TYPE UNITS COMMENTS # Exchange Supply/Demand between two thermal networks: # # Supply temperature from "supply" to "demand" network: xxxx sys bus subsys supplyT WRITE rate SimObject simObject thermal_1.to2Supply.mSupplyPotential double (K) Supply temperature xxxx sys bus subsys supplyT READ rate SimObject simObject thermal_2.from1Demand.mSupplyPotential double (K) Supply temperature # Demand flux from "demand" to "supply" network: xxxx sys bus subsys demandQ WRITE rate SimObject simObject thermal_2.from1Demand.mDemandFlux double (W) Demand flux xxxx sys bus subsys demandQ READ rate SimObject simObject thermal_1.to2Supply.mDemandFlux double (W) Demand flux
The GunnsFluidExternalSupply and GunnsFluidExternalDemand interface works the same as the Basic Supply & Demand interface, just with more data describing the fluid properties flowing between the networks.
PUI SYS BUS SUBSYS VAR_NAME ACTION RATE SIM_OBJECT SIM_VAR_NAME TYPE UNITS COMMENTS # Exchange Supply/Demand between two thermal networks: # # Supply fluid data from "supply" to "demand" network: xxxx sys bus subsys supplyP WRITE rate SimObject simObject fluid_1.to2Supply.mSupplyPressure double (kPa) Supply pressure xxxx sys bus subsys supplyT WRITE rate SimObject simObject fluid_1.to2Supply.mSupplyTemperature double (K) Supply temperature xxxx sys bus subsys supplyX[0-5] WRITE rate SimObject simObject fluid_1.to2Supply.mSupplyMassFractions[0-5] double (--) Supply mass fractions xxxx sys bus subsys supplyC WRITE rate SimObject simObject fluid_1.to2Supply.mSupplyCapacitance double (kg*mol/kPa) Supply capacitance xxxx sys bus subsys supplyP READ rate SimObject simObject fluid_2.from1Demand.mSupplyPressure double (kPa) Supply pressure xxxx sys bus subsys supplyT READ rate SimObject simObject fluid_2.from1Demand.mSupplyTemperature double (K) Supply temperature xxxx sys bus subsys supplyX[0-5] READ rate SimObject simObject fluid_2.from1Demand.mSupplyMassFractions[0-5] double (--) Supply mass fractions xxxx sys bus subsys supplyC READ rate SimObject simObject fluid_2.from1Demand.mSupplyCapacitance double (kg*mol/kPa) Supply capacitance # Demand fluid data from "demand" to "supply" network: xxxx sys bus subsys demandF WRITE rate SimObject simObject fluid_2.from1Demand.mDemandFlux double (kg*mol/s) Demand flux xxxx sys bus subsys demandT WRITE rate SimObject simObject fluid_2.from1Demand.mDemandTemperature double (K) Demand temperature xxxx sys bus subsys demandX[0-1] WRITE rate SimObject simObject fluid_2.from1Demand.mDemandMassFractions[0-1] double (--) Demand mass fractions xxxx sys bus subsys demandF READ rate SimObject simObject fluid_1.to2Supply.mDemandFlux double (kg*mol/s) Demand flux xxxx sys bus subsys demandT READ rate SimObject simObject fluid_1.to2Supply.mDemandTemperature double (K) Demand temperature xxxx sys bus subsys demandX[0-1] READ rate SimObject simObject fluid_1.to2Supply.mDemandMassFractions[0-1] double (--) Demand mass fractions
A couple of notes:
- The mSupplyCapacitance is optional. See the link help pages for how to use these links.
- Note the array range notation on the Mass Fraction terms. This is how Sim Bus transfers arrays of primitives. In this example, the “supply” network has 6 fluid constituents, so its mass fractions array is sized 6, or [0-5] in Sim Bus syntax. Likewise, in this example the “demand” network has 2 fluid constituents, or [0-1].
Most GunnsFluidValve and derived links have a mPosition term that can be commanded by some kind of controller model via the Sim Bus. These controllers are what we typically call a “Signal aspect”, and may model all kinds of valve actuators like solenoids, motor-driven valves, manual valves, etc. Their interface with the fluid aspect is always the same: give us a mPosition from 0 (full closed) to 1 (full open), like so:
PUI SYS BUS SUBSYS VAR_NAME ACTION RATE SIM_OBJECT SIM_VAR_NAME TYPE UNITS COMMENTS # Send valve position from Signal aspect to fluid network: xxxx sys bus subsys position WRITE rate SimObject simObject signal.valveController.mFluidPosition double (--) Valve position xxxx sys bus subsys position READ rate SimObject simObject fluid.valve.mPosition double (--) Valve position
All fluid “impeller” links, such as GunnsGasFan, GunnsGasDisplacementPump, GunnsLiquidCentrifugalPump, and GunnsLiquidDisplacementPump have a similar interface with a pump/fan motor/controller model. The motor model sends a rotational speed to the fluid aspect, and the fluid aspect sends back a resistance torque to the motor. This creates a closed-loop dynamic model. See here for an aspect diagram of a pump/fan — we are talking about its Signal/Fluid interface.
PUI SYS BUS SUBSYS VAR_NAME ACTION RATE SIM_OBJECT SIM_VAR_NAME TYPE UNITS COMMENTS # Exchange shaft speed & torque for a pump motor/fluid interface: # # Motor shaft speed to the fluid impeller: xxxx sys bus subsys speed WRITE rate SimObject simObject signal.motor.mMotorSpeed double (rev/min) Pump motor shaft speed xxxx sys bus subsys speed READ rate SimObject simObject fluid.pump.mMotorSpeed double (rev/min) Pump motor shaft speed # Fluid load torque to the motor: xxxx sys bus subsys torque WRITE rate SimObject simObject fluid.pump.mImpellerTorque double (N*m) Pump fluid shaft torque xxxx sys bus subsys torque READ rate SimObject simObject signal.motor.mLoadTorques[0] double (N*m) Pump fluid shaft torque
…and many more…
These are just suggestions: look at the class declarations for more hints & info about how & when to use what terms.
In general, base class attributes are also suggestions. For instance, GunnsBasicPotential extends GunnsBasicConductor, so mDefaultConductivity is a possible input to GunnsBasicPotential.
