Paraview is great for 3D visualization of data. Thank you for making such an excellent program availible. Thank you for working on Paraview.
I was curious if there was method to export solved data and meshes from HFSS, and import them into Paraview for electromagnetic fields, timesteps, and current distribution–that kind of thing. Personally, I had wondered about the movement of vector fields, over time.
If someone has had decent results, and there is a referring page, or a Wiki, that would also be great. I had looked at HFSS, and was unsure of an import/export workflow.
[Also, it is my hope that the open-source community will continue their efforts to answer the challenge of making a robust electromagnetic solver, as was an aerodynamic solver was done.]
(Thank you.)

ParaView supports a great number of format, you just need to find one that you HFSS software can export to. Which format can you export to ?

@mwestphal , thanks for the reply.
So far, the only viable export I have seen was Ensight, though it errors out, with the following error. I think that the mesh data is elsewhere. Hmm
I think that Ansys really doesn’t want us doing this. I am hoping that someday, there will be an open-source alternative to HFSS, I watch OpenEMS, perhaps someday.
Still, it would be cool to see electromagnetic waves in Paraview’s tetahedrialized volumetric rendering.

You may be able to edit the case file to make it work in ParaView.

I am not sure what version of HFSS you were using when you had problems. In the 2024 release, I haven’t had any issues when exporting Ensight .case files from HFSS and importing them into ParaView.
