run the following command to install dependencies:

conda env create -f environment.yml

• generate_gmsh.py will generate an octet truss sandwiched between two plates like this:

• python run_sfepy.py linear_elasticity.py will run a simulation where the octet mesh is subjected to a compressive strain

• python run_postproc.py strut_test.vtk -b --only-names=u -d"u,plot_displacements,rel_scaling=1,color_kind='scalars',color_name='von_mises_stress'" will postprocess the results to show von Mises stresses induced by the strain

• python run_postproc.py strut_test.vtk -b --only-names=u -d"u,plot_displacements,rel_scaling=1,color_kind='vectors',color_name='cauchy_strain'" will postprocess the results to show Cauchy strain in each element

• sfepy_example.py is an interactive python script which will calculate the von Mises stresses for several different strain values for generating a stress-strain curve
