ParaView-superbuild crashes when .nas files are opened. Problem with VisIt reader?

Development
1

Hello,

I have installed paraview with the superbuild procedure on a MacOS. My main use-case is to use paraview to read Nastran files. To do this, I have enabled VisIt reader by turning on “ENABLE_visitbridge” during the build process.

However, Paraview seems to crash when I “open” the Nastran files. Is this a problem with the VisIt reader or a general bug in Paraview?

I am attaching some Nastran files for you to try out with your own versions:
bulk.nas (330.0 KB)
comwing-wing.nas (158.1 KB)
eb_dyn.nas (6.4 KB)

Please let me know what you think.

Best regards,
Sabyasachi

Thanks for attaching the data and the bug report. It looks like a bug in the VisIt reader and/or an issue with the file:

Dear Cory,

Thanks for following-up on this.

I tried pyNastran which is an open-source tool for visualising nastran files in vtk format. All these files work perfectly in that (find attached an example screenshot).

So, it seems like a bug in the VisIt reader. Has this been reported before? What are the next steps you recommend to take now to get Nastran files working in ParaView?

Best regards,

If you could file a bug report at https://gitlab.kitware.com/paraview/paraview/issues that would be the next step. If someone in the community submits a patch that fixes it, we can get it integrated into ParaView. Otherwise, it will get fixed if a Kitware customer needs it at some point in the future.

Sure, thanks. I have filed a bug report on Gitlab here: https://gitlab.kitware.com/paraview/paraview/issues/18668

Anyone interested can follow-up here and hopefully submit a fix :slight_smile:

Have a good week!
