I need help for a job at the university

hello, I need help to be able to curve a surface in my file I’m trying to look like a coral, so the surface can not be flat, if you can help me I´d be grateful.

Without the original file it is extremely unlikely anyone will be able to help you out. Also a somewhat more in depth explanation of how it works now and how you would like it to work instead would probably not go amiss.
