Applying pressure on surfaces

Post by ufifilters@123 »

Hi all,
Does anyone know how to apply pressure on surfaces in linear elastic model of ElmerGUI?
There is only option for applying pressure on body properties (as body force).

Elmer's model manual chapter 6
https://www.nic.funet.fi/pub/sci/physic ... Manual.pdf

In boundary condition you can add pressure normal to surface or othe BC load conditions.
Normal Force Real
A force normal to the boundary is given with this keyword.

Thanks Kevin

I have tried with normal force equivalent to pressure on the surface (pressure=normal force/surface area). With this option, results are not coming out to be correct. I am trying to find the gap.
Do you know the option of applying pressure directly on surfaces?

Normal force applied to a surface boundary is pressure. Perhaps you can post your case and it can be checked.
