Description
SolverMystran enables usage of the MYSTRAN solver. It may be used for:
- Setting analysis parameters
- Selecting working directory
- Running the MYSTRAN solver
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.
