Hi,
I’m having some difficulty exporting results from GiD’s postprocessing environment. I’m trying to export results in .VTK format so I can view them in Paraview. The export seems to run fine, but then when I open the .vtk file in paraview, part of the results file appears to be corrupted; elements in only part of the model show a ‘speckled’ pattern as shown in the right hand image below. If I import the .vtk file back into GiD I get the same issue, so it’s not related to Paraview.
To be honest even if I can get this fixed, the .vtk export isn’t ideal, as the sets are lost on export so I’m no longer able to view sub-components in isolation within my model. If anyone can suggest a better way of moving results from GiD to paraview I’d be very grateful. It looks like Paraview isn’t able to naturally read any of the other GiD export formats. I might consider creating a script so that Paraview can read GiD postprocessing ASCII files but I’d rather find a solution that doesn’t involve in depth coding.
I have created and calculted a simple case (Kratos structural 3D) of tetrahedra
and exported as Vkt the scalar result on 1-gauss point (‘Von misses stress’)
and then re-imported this vtk in GiD and the result seems the same as the original.
Please, attach a zip with your GiD model including results to repeat the test with your exact case.
What is the GiD version that you are using?
Maybe GiD and/or the vtk import/export plugin has been fixed and you are using an old version
Hi Enrique,
Thanks very much for your reply, and for trying to test it.
Sadly I can’t share the model as it’s commercially sensitive work - hence I posted just a small screenshot of part of it in my previous post. I am currently redoing all the geometry and meshing so I will see whether the export changes with a slightly different geometry. I’ll also try to see if calculating values on nodes rather than GP1 would make a difference.
I’m using GiD v15 which I believe is the latest. Do you think it’s worth trying on an older version as well? I have GiD 14.0.3 installed on another PC I could try.
Sorry I can’t send the model to test, I realise that is a big block to being able to diagnose this at all.
I’ll let you know if I have the problem again when I finish remodelling/meshing next week.
Best regards
James
Instead of your true commercial model, it is much better to debug if you can attach another model, as simple and small as possible,
e.g. a cylinder, with few results
that can be used to repeat the problem exporting in VTK format and re-importing in GiD
