hi

i am dealing with a vibrating membrane with the working fluid as air. I have a problem in dynamic meshing that says negative cell volume found.how to deal with the problem what are the probable reasons for that.

Can anybody suggest something in this regard

thank you in anticipation

You also suggested to use the smooth volume mesh function to reduce inveted elements(negative volume).Smooth the volume meshed many times until the negative volume reduce completely.
