v10.2.13

What's new in this release

• EditorDialog, and touch on the shared flowsheet canvas
• distillation curves ignore traces at the ends; D86 up to 95 %
• FlowsheetCanvas builds for netstandard2.0 (classic); mobile check only on net5+
• three-phase vessel, holdups initialized at level and incompressible liquid holdups in dynamics
• dynamics of vessels with several inlets, pumps on curves and liquid holdups after a pump
• three-phase PT flash when its two-phase seed does not converge
• three-phase PH flash of liquid-liquid states and caller's composition
• orthogonal layout places unconnected instruments next to their blocks
• skip the last-solution copy after each solve in dynamic mode
• PH flash stops when the temperature stalls and the enthalpy error stops falling
• the flowsheet solver keeps the process off Windows efficiency-core throttling (EcoQoS)
• a SolverStrategy option and flowsheet-level external solvers
• the solver strategy on the Solver menu, and flowsheet solvers loaded with the plugins
• implicit Euler steps that run out of iterations are counted and reported
• a column opened from a file seeds its dynamics from the saved profiles
• the column saves and restores its dynamic state between the solves of one step
• the column reports its holdup as dynamic contents
• cubic EOS analytical derivatives follow the mixing sum of each EOS with an asymmetric kij matrix
• one kij per pair in the cubic EOS packages
• Naphtali-Sandholm solver hands back the derivatives of its solution with respect to the feeds
• column sensitivities with respect to the specification values, at the column's own solution
• CAPE-OPEN unit closes the message boxes its solver process shows while it calculates
• mass and energy balances skip energy streams on material connectors
• equation-oriented model interface for simulation objects
• mixer, splitter and vessel equations for the equation-oriented solver
• pump and compressor equations for the equation-oriented solver
• heat exchanger and conversion reactor equations for the equation-oriented solver
• Gibbs reactor without an energy stream in isothermal and outlet temperature modes
• equilibrium and Gibbs reactor equations for the equation-oriented solver
• CSTR equations for the equation-oriented solver
• equilibrium reactor equations evaluate K with the package pointed at the inlet
• heat exchanger vapor fraction modes with their own equations in the equation-oriented solver
• heat exchanger outlet vapor fraction 2 mode reads the inlet temperatures before choosing the hot and cold sides
• heat exchanger vapor fraction modes when the load is cut to the maximum heat exchange
• equation-oriented equations for heater and cooler duty modes, splitter flow specs, component separator and expander
• CAPE-OPEN dialog guard closes the message boxes of the calculating thread
• equation-oriented equations for heater and cooler at a set outlet vapor fraction
• equation-oriented equations next to saturated streams for more units
• equation-oriented exchangers and saturated inlets
• abbreviate the patrons' names on the splash screen
• equation-oriented equations for the PFR and the pipe segment
• more heat exchanger and vessel modes with equation-oriented equations
• Naphtali-Sandholm MESH equations for an equation-oriented solver
• partial condenser liquid distillate in the Naphtali-Sandholm equations
• CapeOpen.dll keeps the parameters' validation code
• subcooled condenser in Naphtali-Sandholm and two feeds on one column stage
• co-current thermal efficiency of the heat exchanger in the equation-oriented equations
• shell and tube rating and fouling factor in the equation-oriented equations
• pipe estimated U, solar radiation and outlet temperature in the equation-oriented equations
• Seawater IAPWS-08 package evaporates seawater and follows IAPWS-08/95 (#122)
• logical blocks' connection lines when the block is flipped, rotated or zoomed (#116)
• MCP dwsim_unitop_connect energy ports count the unit's energy connectors (#121)
• Optimization extensions go to the Flowsheet Analysis menu in the cross-platform interface
• convert a distillation column to a complex dynamic column
• complex dynamic column runs in dynamics; Newton-Raphson without condenser
• lay out the objects added by the column conversion
• stream colour legend scales with the display
• Avalonia compound creator adds the compound and stores it as a user compound
• FluentAPI name for the Asphaltenes (PC-SAFT) Plus property package
• custom compound order (move compounds up and down)
• Reaction Finder sets the heat of reaction of the reactions it suggests
