Hello,

 

i would like to load a pressure on the interface of my system. Is it possible to put a pressure on a surface, without that this surface is an inlet or outflow?

 

Thx

    I am not sure if it really makes sense to have this type of BC. Are you trying to simulate a flexible body ?

     

    Anyways, AcuConsole does seem to allow that kind of BC. You would need to set the correct precedence if using a mix of BC.

    You can also apply pressure using Element Boundary Condition, but it is a bit dangerous and not recommended to do so for internal nodes (Nodal BC) and or surfaces (Element BC).  What is the scenario where you want to use a boundary condition on an internal surface?
