Opis

Polecenie SolverMystran umożliwia używanie solvera MYSTRAN. Można z niego skorzystać do:

  1. Ustawienia parametrów analizy.
  2. Wybrania katalogu roboczego.
  3. Uruchamiania solvera MYSTRAN.

Instalacja

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 can be installed through pip:

  1. Open a Command terminal in your FreeCAD\bin folder.
  2. Enter: python -m pip install pyNastran
  3. It will be installed in the FreeCAD\bin\lib\site-packages folder.

hfcMystran can be downloaded from its github site as a zip file. Unzip it and place it in the FreeCAD\Mod folder.

Quick test

After installation you can select Utilities → Open FEM examples in the FEM Workbench. 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.

$pyNastran: version=msc
$pyNastran: punch=False
$pyNastran: encoding=utf-8
$pyNastran: nnodes=0
$pyNastran: nelements=0
