Hello John,

very disappointing that the Problem from 0.19.18xxxx was solved in 20802 and now has the same Problem again in 20839. Any Idea who could take care of that?

could you please send me the Help->About->Copy to clipboard information? I'd like to file a Bug,... or if you like you can do it yourself?

Thanks a lot for your help, great to have feedback.

Best Regards, Seppel

Hello fandaL,

not sure, I changed it to 10kHz in the preferences when I was doing some simulations earlier, if I remember right... so that was my fault I guess.

Default was however 1Mhz or something like that. Guess it's always limited?

Thank you very much for your amazing help, awesome :D Not it works, and I understand what was wrong. Very nice!

Best Regards, Seppel

Just the ccx is not included in the Zip file. Last time there was no gmsh.

I copyied the ccx from the old version to a folder in the serch path, so no problem.

Hello John,

but I think that is an issue when FC is released the next time. I guess there is a script compiling/copying all the packages,... . Maybe it's a manual process and that's the issue, if it would be automated that wold solve it properly?

ccx and gmesh are not in the Libpack, so I have to download and mange them separately. Unless someone pings me I don't update them often. Its better if the user manages these packages themselves, and set the paths to the executables in prefs.

Anyway it will be fixed in the next bundle.

the normal windows package includes ccx as well as gmsh! Might be if you switch between installed, conda, whatever package ccx or gmsh binary path is just wrong!

I've had some issues lately including these in the Libpack builds. Hopefully this is fixed for a while :(

11:41:49  Problem on frd file import. No nodes found in frd file.

The code for Calculix written by FreeCAD is as follows:

The default Megaherz gives the same issue.

Is this problem showing its head again or am I doing something wrong? Any ideas for me?

Thanks in advance!
