Description
The SolverMystran command enables usage of the MYSTRAN solver. It may be used for:
- Setting analysis parameters.
- Selecting working directory.
- Running the MYSTRAN solver.
Installation
You can get the Mystran Windows executable here. Put the folder where you place Mystran.exe in the Windows's PATH variable.
The SolverMystran also needs two other packages:
- pyNastran - to write out case file.
- hfcMystran - to read in Mystran's NEU result file.
pyNastran can be installed through pip:
- Open a Command terminal in your FreeCAD\bin folder.
- Enter:
python -m pip install pyNastran
- It will be installed in the FreeCAD\bin\site-pakages folder.
hfcMystran can be downloaded from its github site as a zip file. Unzip it and place it in the FreeCAD\Mod folder.
QuickTest
After installation, in FEM workbench, you can select Utilities\Open FEM examples to open the FEM examples window. Under Solver\Mystran, you can find some working Mystran examples.
Usage
ToDo
File function
Under Mod\Fem\femsolver\mystran, there are these files:
add_con_displacement.py
add_con_fixed.py
add_con_force.py
add_femelement_geometry.py
add_femelement_material.py
add_mesh.py
add_solver_control.py
writer.py
solver.py
tasks.py
The function of each file are:
writer.py - main control file
model = BDF()
model = add_solver_control.add_solver_control(pynasf, model, self)
model = add_femelement_geometry.add_femelement_geometry(pynasf, model, self)
model = add_mesh.add_mesh(pynasf, model, self)
model = add_femelement_material.add_femelement_material(pynasf, model, self)
model = add_con_fixed.add_con_fixed(pynasf, model, self)
model = add_con_displacement.add_con_displacement(pynasf, model, self)
model = add_con_force.add_con_force(pynasf, model, self)
BDF() - Create empty case file.
