This could have various reasons ...

You use the stable version of FreeCAD ...

FEM has seen hundreds of updates and fixes and prechecks in version 0.17 Thus it is highly recommended to use the latest development version 0.17.xxxxx if you really would like to work with FEM in FreeCAD.

Hey Bernd

Even i agree with what you said. But the latest official release for windows and OSX is 0.16.

So I'm not sure regarding upgrading. Though if you have been facing such a issue and it was solved by the way you said i'm up for it.

@shivaksingh, The official releases are just snapshots taken in a quiet period of development (I'm open to correction :D ). Don't be afraid of using the most up-to-date development version, especially for FEM workbench.

There where hundreds of fixes and improvements fir FEM in 0.17.

Actually noone from the regular FEM users uses FreeCAD FEM with 0.16 release. As said before for FEM the use of latest 0.17 dev version is highly recomended!

I do not even have 0.16 installed.

But this only applys to FEM.

You can simply install development version from https://github.com/FreeCAD/FreeCAD/releases where is file like this
FreeCAD_0.1710887_x64_dev_win.7z
which you only unpack in your computer and launch \bin\FreeCAD.exe
It does not affect your 0.16 installation.

If you will use 0.17, contrary to the Manual (for 0.16 version) it is faster to create mesh after applying constraints. Use GMSH for meshing (icon https://www.freecadweb.org/wiki/File:FE ... mShape.png )

When I'm trying to run a file made using 0.16 version. Its asking to convert the file to be 0.17 compatible. When i clicked yes it changed my part.
I had designed H shaped geometry and was left with L shaped one.

Though thanks for your help. I redid it and 0.17 is amazing.

Regards
