Error message - simulation of quarter of geometry of plates


#1

Hello everyone,
I created a project “Plates” to experiment with various geometries, loads and boundary conditions. When I use the whole geometry I received results, but when I use a quarter of geometry and planes of symmetry, I receive an error message. I would be grateful if someone reviewing my project and found my mistakes.

Thank you very much!

Hi @atanas_kuzev,

In most cases symmetry should be implemented with the “fixed value” constraint rather than the “symmetry” constraint. For an explanation of this seemingly counter intuitive advice please see this thread.

Here are some screenshots showing how to set up symmetry with the “fixed value” constraint.

If you get stuck I can share a working copy of your simulation.

Regards, Ben

Hi Ben,
I used your constraints and I received results.

Thanks!
