pressure on surface

[crave]

I have a problem defining a surface. How can you create a surface where you can define a pressure onto it? On an excisting surface I want to put a circular pressure on it. I think that you must create in advance a surface and then define a presssure to this surface. But when I do this, the force doesn't work on the part... that surface is just going through the part. How can I fix this?

Thank you in advance

If you just mesh one surface of the part yes it will go thru the part but if you use the midsurface feature and mesh all surfaces of the midsurface feature or use solid elements for the entire part it will not do that.
