did some development on https://github.com/berndhahnebach/FreeC ... e/fembeams Attached the file to test. Change the rotation in the rotational object and all beam rotations will change.

beam analysis including beams in z-direction does run :-) We will hopefully can integrate this still in 0.17, since it fixes an very very old limitation in beam analysis :-) I just need to prepare the PR.

@FEMuser:
I do not have an email from you. In your git commit was not the email of your github account. Thus if you click in https://github.com/berndhahnebach/FreeC ... s/fembeams on your name github can not assign your account. It would be cool if you could provide the email of your github. Try to click on the names in https://github.com/FreeCAD/FreeCAD/commits/master it will show the commits of this user, but only if the email is the right one in the commit. You can sent it by email.

Hope the little one is fine :)

I just tried the beam cube above posted by Bernd in the latest master.

When writing out the INP I get the following error.

Code: Select all

raceback (most recent call last):
  File "C:\Freecad\Freecad_compile\Mod\Fem\PyGui\_ViewProviderFemSolverCalculix.py", line 262, in write_input_file_handler
    fea.set_analysis_type(self.solver_object.AnalysisType)
AttributeError: 'FemToolsCcx' object has no attribute 'set_analysis_type'
Tried to insert standard and new experimental solver object and got even more errors
Any Idea what changed ?

Thanks
Michael

this dev was removed from ccx tools with git commit 88051e01 I do not know why you get this message. May be you have mixed modules in your Mod folder. Use latest master, or at least try to clean the FEM build dir and rebuild.

BTW: recreated the example and found another small problem. See https://github.com/FreeCAD/FreeCAD/pull/1311 commit https://github.com/FreeCAD/FreeCAD/pull ... 52f25102fb

I had a trouble with beam orientation formatting in inp file - see this post https://forum.freecadweb.org/viewtopic. ... 93#p396715

It is written here: https://github.com/FreeCAD/FreeCAD/blob ... r.py#L1736
and again for other cross sections few lines below.
