Linear elasticity solver in 2D

[Martin_]

Dear Elmer users & developers,

I would like to ask what is the default mode in which the 2D linear elasticity solver works. If I understand it correctly, the solver is in plane strain 'mode' by default and to perform plane stress computation, I need to set

Code: Select all

Plane Stress = Logical True

Can you please confirm this (or, if I'm wrong, tell me how to set up a plane strain test case)?

The manual also says that for boundary conditions, either displacement or force can be applied. In this case, I suppose that force is in [N]. How can I apply pressure/stress on the body of my model?
Thank you very much.

Best regards,

Confirmed.

The unit of force in BCs is [F]/[A] i.e. Pa in SI units. Pressure as a keyword is taken by the N-S equation.
