Linearized stress plot problem in 0.18

[makkemal]

It seems something have changed in the VTK post filter data along a line
The plot can't seem to find the data ?
Does anyone know what changed ?

The names have changed ... git commit f445e34 fixes it in 0.19

BTW: It is not possible to set up two DataAlongLine filters. If a second one is added they go crazy and shown wrong colors.

Ok thank you

How about a small tutorial, what is the linearized stress plot useful for. We might have some informations and examples on the forum alredy, but it would be cool to collect it in a small tutorial!

Could you confirm this?

I am working on the tutorial

I can confirm that you can only do 1 data along a line filter otherwise thing go haywire.

The user-defined plot has been broken.
For ASME you want to do P1+P2+P3 < $S where S is material allowable stress
It gives the following error.

Code: Select all

Traceback (most recent call last):
  File "C:\Freecad\Freecadbin\Mod\Fem\femguiobjects\_ViewProviderFemResultMechanical.py", line 442, in calculate
    del s1x, s1y, s1z, s2x, s2y, s2z, s3x, s3y, s3z
UnboundLocalError: local variable 's1x' referenced before assignment

Although it still creates the field

[bernd]

which FreeCAD version?
