I can not find it ... AFAIR ... if the mesh has lonley nodes which do not belong to a element these nodes are not exported to the result mesh. The nide count of the result mesh than differes from the mesh to analyse. What does Mystran do with lonley nodes? Does it accept a analysis with a mesh eith...

@mesheb82, which OP2 flavor will be used? MSC or NX? Will we be able to select it with a bulk parameter?

how is that possible?

mainly the return value of this method is needed ... https://github.com/FreeCAD/FreeCAD/blob/master/src/Mod/Fem/feminout/importCcxFrdResults.py#L245 When I debug the output of ``importCcxFrdResults`` ran on ``thermomech_spine.frd`` I see that model is described ("Nodes" and "Tetra10E...

That is a great news!

The NEU reader from this AddOn can not be integrated into main FreeCAD because it is GPL3 and FreeCAD is GPL2. If this is an issue, I have a NEU parser (under MIT, but I can change if required) there : https://framagit.org/numenic/femap_neutral_parser I'm using it for my personal projects right now...

but that would mean to have an OP2, which MYSTRAN still not supports for now.

latest weekly LP win build has pyNastran and MYSTRAN.exe included, means start FreeCAD, open some FEM examples and run with Mystran :D I managed to install pynastran, and apparently, loading MYSTRAN example and running it runs fine! congratulations! Now, rsults are in the /tmp/XXX folder, and I can...

ahh may be you just used the wrong Name. The package is called py N astran not py n astran Thanks for answering, bernd I just found how to install a python package after compilation: starting ``FreeCADCMD`` from bash will open FreeCAD embedded python console, from a TTY . Then, I can import pip; pi...

I'm compiling freeCAD now from source and I can't wait to try it out.

I'll grab that appimage build right away.
