How do I do that

basically what you did now(most often the text is removed and the word ping is added).
I have see some people who can ping people from a macro but i don't where that one is coming from...

I like to use @TheMarkster's Pinger macro (it's in the addon manager under 'Macros')

Edit: As on this edit, @yorik enabled phpbb 'mentions', so all you need to ping someone is to prepend an @ in front of their forum usename. No need for pinger macro anymore

If Bernd has not been active on the forum for a month then he will have a very good reason for that. I therefore don't want to bother him and am trying to understand the new input writer code on my own.

Bernd committed a major change to the FemInputWriterCcx on 19 February last year:

https://github.com/FreeCAD/FreeCAD/comm ... b8ba22117c

This affected 6 files with 29 additions and 155 deletions.

I can now locate the material data, but not yet the elements that go with that. I wrote a CCX input file to see if I can trace back where the element data comes from and how it is linked to the material in FC.

Now here is my latest challenge: Object ccxwriter gets passed around more than 100 times in 23+ files, but I cannot find the Class definition or any other declaration related to it.

Can somebody help me find it and/or give me some tips on how to unpick this Russian doll?

I can't test that right now but git grep should get you to the definition quickly

Thanks, same search results as with PyCharm, but still no sign of an assignment or initiation of ccxwriter. I am at a loss how it is used everywhere without any import statements.

Check src/Mod/Fem/femsolver/calculix/writer.py

Edit ccxwriter is used as a local variable (TBC)

Sorry, but I don’t see ccxwriter anywhere in that file. Also … if it is a local variable how does it get used in 22 other files without import of the relevant module?

You won't see ccxwriter definition if it's used like that: You have to check how to function is called: ccxwriter is self. Silly question, but are you familiar with python self?

I'll be away for a while, but if you post the part of the ccx input file I or someone else might try to help you. Element data is generated from mesh IIRC and how it's linked with the material - I'd check the CalculiX docs.

https://web.mit.edu/calculix_v2.7/Calcu ... node7.html <- an example

"material is assigned to the element set Eall by means of the keyword card *SOLID SECTION. "

P.S. I found your question now. You want to extract material parameters from a ccx input file?
Material para,enters are written in: src/Mod/Fem/femsolver/calculix/write_femelement_material.py
Then the definition is used for elements - name of the material is the handle.

Thanks. That’s the bets Python tip so far.

Not so silly. I am a FORTRAN guy and it shows.

I wrote fcFEM in Python (the FORTRANIC way) carefully avoiding objects and classes, but using list comprehension and other nifty Python tricks.

I read several books about Python, but still fell in the OOP trap.
