Physical Simulation Steps

training and validation data is overlapping
seperate some additional test data apart from training and validation data?
make geometry/mesh/analysis of deformation in Simcenter 3D
close every file in Simcenter 3D
Heeds (Anaylsis Portal: Simcenter 3D_2306)
1. Process -> Simcenter 3D
2. Input sim file (named Hachathon on desktop)
Select tags and variables
1. press auto tag -> CAD expressions (lattice_d_cell, lattice_d_rod, scalingfactor_x_y, lattice_num, and all)
2. select min/max intervals
Output (response)
1. select blue icon and everything
Run
1. study->methods->design set-> add item -> put numbers in the variables) and experiment with it
2. go to RUN-tab and run

variables (CAD expressions)	computer 1	computer 2	computer 3
lattice_d_cell [1.9,2.75]	2.375,2.75	1.9	1.9,2.375,2.75
lattice_d_rod [0.2,1.2]	step 0.05	step 0.05	step 0.05
scaling_factor_YZ [1,6]	3	3	6
lattice_num [1,4]	2	2	2
load	100N	100N	100N

the lattice_d_rod has the highest impact on porosity

Young modulus

The first a few lines are CAD expressions/parameters, then the displacement vector $U$. We need to calculate the Young modulus/effective stiffness $E$ from the mean value of $U$, i.e. $\Delta U$ $$E=\frac{\sigma}{\epsilon}=\frac{FU_0}{A\Delta U}$$ where $\sigma = \frac{F}{A}$ is the stress, F is the fixed load on area $A =$ h_total_z $\times$ w_total_y (depending on scaling factor), and $U_0$ is d_total_x
Porosity

For presentation, we need to calculate porousity $P$ $$1-P = \frac{V_{mesh}}{V_{total}}$$ where $V_{mesh} = V_{lattice} + 2V_{plates}$, $V_{total} = V_{cube} + 2V_{plates}$ $$V_{lattice} = 8\times\frac{\sqrt{3}d_{cell}}{2}\times\pi\times(\frac{d_{rod}}{2})^{2}\times ScalingFactor^{2} \times LatticeNum$$ $$V_{cube} = d_{cell}^{3}\times ScalingFactor^{2} \times LatticeNum$$ $$V_{plates} = 1.5 \times d_{cell}^{2}\times ScalingFactor^{2} \times LatticeNum$$ }
