CalculiX (.frd) and pyvista

I am pleased to inform you that I have successfully added native support for reading .frd files directly into PyVista.

This feature is currently slated for release with version 0.48, which is expected to be available around April. This implementation will allow users to load .frd file seamlessly without requiring external conversion scripts or intermediate steps.

Now that version 0.48 is officially available, I wanted to take a look at the native import feature. I have a question before I get started:

Is there a way to import only specific elements and their associated nodes? For example, if I have an assembly where I only want to analyze one component later, can I import that component individually into PyVista? I have an element group (ESET), but as far as I know, these aren’t saved in the FRD file.

Did you try to limit your output by *node file,nset=nset_of_your_eset?

Best,

Hi stoli, Thanks for your hint. I didn’t know this kind of filter could be added. I just read through the manual for *NODE FILE again, and now I have two new questions:

  • Right now, I only have the part as an element component. Is it possible to convert it down to a node component during or after solving?
  • If I have an assembly and there are several individual parts that I’m interested in and would like to process them further independently, can I create a *NODE FILE for each part and possibly give them their own names? I haven’t found anything like that in the manual.
