Thank you for your advice. I managed to solve the simulation with increased deformation across the surface. I reduced the element by having a body sizing with element of 0.25mm. It is very small which increased computational time to 3 hours to solve the simulation. The ridges are very small with a thickness of 0.3mm and width of 0.5mm.I tried face meshing on the rdiges to have small element just on the ridges, but the solver could not mesh it properly. See image below on the final mesh. By any chance do you know a workaround where I can have small meshing just on the ridges instead of the whole part?
For the contact setting, I changed the contact to frictional contact between the ridges and the opposite face they press against. I kept the frictionless support on the side and one edge as a fixed support. See images 3 and 4.
3) Frictionless support
4) Fixed support
The result are seen as below
5) Deformation on part with ridges.
6) Deformation on part on the oppositre face that the ridges press against.
Do you know why I dont see the ridges being planted on the opposite face that they press against. Im trying to design the ridges to press against an elastomer (Viton) to provide fluidic sealing. My objective is to know how much pressure that the ridges exerted with different bolt preload. See image 7
7) What I expected to see on the opposite face that the ridges press against in red drawing (excuse my poor drawing).
It will be great if you could help me to understand this result, please.
