Re: update on FreeCAD + OpenFOAM fluid dynamic computation
Hallo,
would love to see a FreeCAD interface for OpenFOAM!!!
For all how do not know what to do with OpenFOAM here some examples where FreeCAD was already used to draw the geometry:
https://www.youtube.com/watch?v=uV84p_GTUPU
https://www.youtube.com/watch?v=KeEp6EJuIxU
and a more OpenFOAM specific introduction
https://www.youtube.com/watch?v=Kznljrg ... Du3yUq7YoT
There are also other solvers such as one for electromagnetics. This would extend the FEM simulation range for FreeCAD dramatically.
http://www.openfoam.org/features/standard-solvers.php
There is also a nice python-interface to control and manipulate OpenFoam pyfoam: https://openfoamwiki.net/index.php/Contrib/PyFoam
Please let me know if there is something to beta-test for standard FreeCAD users.
Thanks in advance,
HoWil

Re: update on FreeCAD + OpenFOAM fluid dynamic computation
OpenFOAM for FreeCAD finishes stage II development (2016-04-17)
This is an early preview, only for people with experience of OpenFoam.
Test instruction could be found at
https://github.com/qingfengxia/FreeCAD/ ... /Readme.md
I would love to see some feedback for stage III development, see roadmap:
https://github.com/qingfengxia/FreeCAD/ ... roadmap.md
A video preview of OpenFoam plugin for FreeCAD Fem workbench
http://www.iesensor.com/FreeCADDoc/oepn ... engXIA.mp4
The code will attempt to merge with master for version 0.17 after review. However, the OpenFoam related code is independent from CalculiX, except for the Material class. I plan to developed a general FemMaterial model (not yet finished), ultimately for multiphysics modeling in FreeCAD. Rebase to master will be easier than before.

Re: update on FreeCAD + OpenFOAM fluid dynamic computation
Hallo qingfeng.xia,
I will test your work in the next days.
The video looks very promising.
How much work will it be to use other openfoam-solvers like the one listed here https://openfoamwiki.net/index.php/Main_ContribSolvers ?
BR,

Re: update on FreeCAD + OpenFOAM fluid dynamic computation
Hello,
I managed to compile the latest build on a ubuntu 16.04.
Unfortunately Freecad crashes when I try to reproduce the simulation in your video.
It crashes when I try to assign the fluid boundary condition. I get the following messages in the terminal (see below).
I also noticed that all elements of the simulation (mesh, material,..) in the model-tree-view are not grouped. I grouped it manually.
I can create a MechanicalAnalysis (where all elements a grouped) but it seams that the results can not be loaded into Freecad after running calculix. I saved this model and opened it in my local Freecad 0.16 and could run the simulation without problems.
Do you have any clue why the open-foam version crashes while the calculix version does not?

Thanks very much for testing. I think you can check if FemGui/FoamCaseBuilder, this folder has been copied into your FreeCAD FemGui binary dir.
It seems the FoamCaseBuilder as a python module is not accessible to Python. For quick test, I make a symlink to this FoamCaseBuilder folder to the FreeCAD/build/ (which I did not install to system wide, but test in build dir)
For C++ code sigsegv, I am not sure. I recently upgrade my ubuntu t0 16.04 will test it this weekend.

Re: update on FreeCAD + OpenFOAM fluid dynamic computation
@quingfeng:
All CalculiX related code was spitted from FEM base code in FreeCAD master. Means adding a new solver is possible only by adding code without changing lots of code. See as an example the z88 solver.

Re: update on FreeCAD + OpenFOAM fluid dynamic computation
Hi, I just compiled foambuilder_pre2 on ArchLinux. The TestCase from the video works without Problems. To execute FreeCAD from the build folder (in source build) i had to execute FreeCAD like so:
That should resolve the problem mentioned by HoWil.
Code: Select all
bin/FreeCAD --python-path=src/Mod/Fem/
