i need to try FEM workbench using newest development version in windows, but i get an error message when i prepare for meshing even Netgen stand alone version has been installed separately.

as @bernd as pointed out, a workaround is to use FC 0.17 4445 here
https://github.com/FreeCAD/FreeCAD/rele ... dev_win.7z
and generate the mesh there, then copy mesh and model to the latest FC and make FEM analysis in latest FC

@sgrogan is going to be able to build FC dev with ng support... hopeful some more little time to wait

hi easyw-fc,

thank you for quick response, currently i'm using FreeCAD_0.17.8591_x86_dev_win

so there's three option for me as most the others ordinary end user:
1. change my windows from 32bit to 64bit and use 4445 provide by Bernd
2. hope some expert for kindly provide binary for windows 32bit
3. wait for stable release in the next year

regards,

I think you have more confidence than me. I think I'm close with the x64 version. Hpoefully after that is working the 32 bit will be straight forward

1. wait until Sgrogan provides up to date FreeCAD compiled against nglib. Which could happen in a few days, maybe, may be not. Maybe it will happen in a few weeks. No one knows until it had happend. FreeCAD motto is: "It is done when it is done." Nglib is a beast. I had lots of trouble to compile FreeCAD on Linux Debian Jesie against nglib too.

2. Download the latest working FreeCAD compiled against nglib, which is 0.17.7745. You can download it on the same location like the up to date FreeCAD: https://github.com/FreeCAD/FreeCAD/rele ... g/0.17_pre Use this version for meshing and copy paste the mesh into the up to date FreeCAD. You can also save the mesh as unv and import it in the up to date FreeCAD.

3. export your geometry to brep. Use netgen or gmsh gui to mesh your part, export to unv and import the unv into FreeCAD. A FEM mesh object will be created.

In any case it is strongly recommended to use the latest development version if you work with FEM. There is a lot of bugfixing and development going on these days. If you work with latest develpment version please report any bug you may encounter.

cheers bernd

Ahh if you just would like to play you could use the included example.

- start FreeCAD
- change to StartWB
- load the 3D FEM example
- A mesh is included already
- play with constraints.

sorry I didn't notice you were using win32 version...
so you have to download the 32 version of 0.17 4445
https://github.com/FreeCAD/FreeCAD/rele ... dev_win.7z
and generate the mesh there, then copy mesh and model to the latest FC and make FEM analysis in latest FC
... have both releases of FC open, then simply copy and paste between 4445 and the latest ...
you can then save the analysis in FC latest

thank you all,

version 7745 working fine, try follow suggestion to reopen in latest development version 8591 it's freeze and hang on seeking dependencies even both FEM preferences are the same.

This should not happen at all. Would you post the file and your full FreeCAD version information

You should not save any FEM objects with version 7745 except the mesh. There have been tons of commits made in FEM. Use 7745 for meshing only!

hi Bernd,

i just reopen my previous version model using latest development version from FCStd files, try to rerun analysis but it hang up. next time i'll try using unv mesh only.
