[SOLVED] ParaView Post Processing

Recommended Posts

hi all,
I'm using Paraview for post-processing AcuSolve result.
The process i used is:

1. use AcuOut to convert AcuSolve result into Ensight format.

2. input Ensight format file into Paraview.

 

Basically, i can see the result in Paraview for both steady state and transient analysis.
However, for simulations which contains mesh movement, i cannot see the moving mesh in paraview. Everytime when i move to the next frame, the mesh disappear.
Does anyone have the solution for my case?

This is the settings in AcuOut i used:

Result loaded in ParaView:

Mesh dissappread when i move to the next time steps:

Thanks in advance!

This is actually a ParaView bug.  The Ensight reader doesn't properly handle the displace coordinates option.  There are a couple work arounds available.  The easiest is to write the data out using CGNS format instead of Ensight.  The other option would be to continue using Ensight format, but deactivate the "Mesh Motion" option in AcuOut (alternatively, you can just comment out the corresponding line in the .case file and not re-run the conversion).  Then, you'll be able to displace the coordinates in ParaView manually by adding the mesh_displacement vector to the coordinates vector at each time step.  This can be done using the Calculator filter by enabling the "Coordinate Results" option.

hi cfdguru,
your solution worked. i used CGNS format instead of Ensight.

Thank you very much! :D
