Description

SolverMystran enables usage of the MYSTRAN solver. It may be used for:

  1. Setting analysis parameters
  2. Selecting working directory
  3. 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.
