Testing oofem solver

[johnwang]

Hi,

I got oofem solver from this folder https://github.com/berndhahnebach/FreeC ... lver/oofem
also this file: https://raw.githubusercontent.com/bernd ... femMesh.py

1. Under my FreeCAD\Mod\Fem\femsolver folder, I moved the z88 folder outside FreeCAD.
2. Copy the importOofemMesh.py into the Mod/Fem/feminout folder.
3. Copy the oofem folder in and rename it to z88.

Now I'll treat oofem as z88.

I don't have z88 in my computer.

1. Under new z88 folder, there are only 4 python files: init, solver, tasks and writer.py. Check these files, if it mention oofem, change it to z88. Someplace is Z88. Not all need to be changed.
2. Find oofem.exe in my computer, rename it to z88r.exe

Start FreeCad, go to FEM z88 solver setting, found the renamed z88r.exe.
In FEM workbench, open one z88 example, write out the case file. If it complains about material lacking of thermoExpansionCoeff, change to one that does has that value. Run the solver, you will get a result.

Cool.

John

do not use just the oofem directory. The branch is rebased on master thus take all fem. Than you wll have oofemimportMesh and the examples as well see this post how to update FEM ... https://forum.freecadweb.org/viewtopic. ... 60#p521908

it is much simpler ... just use the property editor and add the binary preferences for oofem exact the way as they are there for mystran or gmsh.

No need to change oofem.exe to z88r.exe. The preferences askes for 'binary path'. I normally think path means folder. But it is actually the exe file.

I got this error:

Code: Select all

not need to use any preference at all. Just uncomment this line and add your binary path including the binary file. https://github.com/berndhahnebach/FreeC ... sks.py#L92

not need to use any preference at all.

Then if I set up a FC3rd button, rename the oofem folder as FC3rd, change solver.py as:

Code: Select all

#def create(doc, name="SolverOOFEM"):
def create(doc, name="SolverFC3rd"):
    return femutils.createObject(
        doc, name, Proxy, ViewProxy)


class Proxy(solverbase.Proxy):
    """
    The Fem::FemSolver's Proxy python type, add solver specific properties
    """
    #Type = "Fem::SolverOofem"
    Type = "Fem::SolverFC3rd"

Also add FC3rd into FreeCAD\Mod\Fem\femsolver\settings.py

It will work.
