Elmer Discussion Forum

Hi. When running Linear Elasticity Harmonic Analysis the VTU exported file appears to have poor data that does not compare to the solution as viewed in ElmerPost.

• Running Elmer on Arch Linux amd64, installed through AUR (compilation and installation commands scripted in the PKGBUILD).
• Elmer Version: 8.2, Compiled: 2016-06-23

Here a comparison of how the Harmonic Analysis solution appear in ElmerPost end ParaView respectively:





The problem can be reproduced also by setting case.vtu as Post File in the Simulation parameters. I am not sure whether it is a bug or me doing something wrong, but I am getting crazy around this for a week without finding anything wrong. I guess it could be something wrong with ParaView as well but I lack the experience to make sure about it.

See attached file with minimal example: .

Hi CrocoDuck

Thanx for reporting! There is indeed some challenge to get it to work. The feature uses the same parts of the code as the eigenmode part but you have to add a keyword to make it work to the Solver section Now since few minutes this has bee fixed in the devel branch. Also the naming is improved. So if you recompile your case should work as is.

Hi Peter, thank you very much! I will test the devel branch at my earliest occasion and report back.
