Issue with plot hide

[user2705]

Dear all,

I am running an input file with tetras just to see if my geometry is working for subsequent analyses, and I have quite a lot of elements and nodes.

It seems that the computations are performed ok, but when I plot in interactive mode hide after persp, feap crashes with the error in the attached figure. When I use cwire, it works.

I also tried exporting to paraview, I get the same error.

What can be the cause? Memory or something else? Attached, I am sending you the input files.

Best regards and thanks in advance

What version of FEAP are you using?

I ran your problem with version 8.6 and there was no problem.
See the attached images of the mesh and the v.Mises stress after solving.

One item to think about is that you should optimize your bandwidth to
get a faster solve.  I add the OPTImize command after CHECk and it
sovled in a second or two.

Dear professor,

Thank you for the prompt reply.

I am using Feap 8.4, Visual studio 2012, and Fortran composer 2013 on Windows 11 Pro.

I added the optimize command and it runs faster.

Still it crashes with 'hide' in interactive mode, with '_wire' there is no problem.

Update: I tried coarser mesh, it works, as well as output to paraview. So it is probably the memory issue and the PC I am using.

Best regards

I tried your problem with Release 8.4.1d and it worked fine for me.  Perhaps your version has been corrupted in some way.  You may want to try a clean build with the download-zip.  Notwithstanding, I recommend that you upgrade to the current version 8.6 which fixes many bugs in 8.4.

Dear Feap Admin,

Thank you very much. I will try a clean build and upgrade to 8.6.

Best regards
