Elmer Discussion Forum

I have probably found the issue why I am getting incorrect results. In your case @kevinarden you have a file called mesh.director to specify the normal vector. Could you please tell me how can I make such a file from my mesh?

I think maybe 2 weeks ago. I install it from the repository. I will update the solver and try again.

I assume that these results are from your simulation, not mine? Because I got really strange numbers no matter the mesh.

Sorry guys for disturbing you but I am trying to reproduce this case on my own and I got an incorrect results. I was searching for mistakes for a long time and I cannot find any. Would you be so kind to have a look at my simulation to help me what am I doing wrong?

Thank you all for your responses I really appreciate your help and advice. The model is correct now and I managed to understand how the DNU boundary conditions work. Looking forward to do some more complicated cases with Elmer

Thank you all for ideas, I will try to tweak my model according to them. I will let you know is change of coordinate system or normal vector helps with anything. If not I must be happy with blocking an AC edge

Actually that is not true. I managed to obtain correct result without locking AC edge with Ansys and Code_Aster and friend of mine got correct results with use of Abaqus (please see attached screenshots) so probably model in Elmer is incorrect.

Thank you for your responses. I have managed to simulate this model thanks to your helpful post. I also found dr Gupta tutorial which explain the syntax of shell solver. I left the link, maybe somebody would find it useful: https://www.researchgate.net/publication/320198436_User_Guide_for_Elastic_Sh...

Dear all, I am a new user of Elmer and I am really impressed by it;s capabilities. I would like to do a model according to this link: http://www.caesarsystems.co.uk/NAFEMS_benchmarks/le3.html I am aware of Elmer ShellSolver. I have read the ElmerSolver documentation and unfortunately I didn't find a...
