TestRequest and CodeReview, Exact cload for edges

[bernd]

I finished the cload implementation for edges. Did some changes in ccxwriter as well

I may add some files to test in another post

So much FEM so little time, it's hard to keep up.
I put some win builds here:https://github.com/sgrogan/FreeCAD/rele ... .16-femdev

I'm reading the code and in general it looks fine. I'm not analyzing how it works - it's too much for me today
I found one thing that doesn't look nice - sortlistoflistvalues
I think there is no need to use a new list:

Code: Select all

>>> l = [[1,2,2,0],[2,5,1,2],[3,4,9,3,1],[9,2,5,7]]
>>> for e in l:
...     e.sort()
... 
>>> l
[[0, 1, 2, 2], [1, 2, 2, 5], [1, 3, 3, 4, 9], [2, 5, 7, 9]]

Back to the code...

Hi, very useful features, those builds are for Windows?

Hi, very useful features, those builds are for Windows?

Yes, I can't build a proper debian or RPM package yet. Let alone an OSX app. So from me its always windows.
Please test well. I'm not familiar with the structural workflow w/ beam and shell elements or edge loads. We all need to keep the feature requests to a minimum during testing.

I tried this when I was developing the def. I would swear it did not work when tried it

I'm gone change it in in further version ...

I cannot find a link, but python sometimes does something unexpected when operating on parameters passed with a function, so you might be right that it doesn't work in a certain situation.

line-load--shell-mesh.fcstd
Seems to work.

line-load--solid-mesh.fcstd
When I run quick analysis "Write .inp file and run Calculix ccx", it gives me result. When I click to "Dialog to start the calculation of the mechanical analysis" it doesn't open task window to start analysis, only reports:

Code: Select all

Running the Python command 'Fem_MechanicalJobControl' failed:
Traceback (most recent call last):

But when I create new MechanicalAnalysis and copy/paste all content to it, all works normally.

line-load--beam-mesh.fcstd
Similar problem with the same error report.
I'm able to do the same trick, but I must create new BeamSetion by hand, because I cannot paste it to the new MechanicalAnalysis.

Last note: I don't see anywhere units for Line load yet.

That's OK - there were quite a few changes recently and it's normal and expected behaviour.
If you see any errors after creating the new analysis and moving the content then we have a bug.
