    What's wrong with my simulation?

    Wai Yan Htat

      I'm doing simulation for tank pressure test.  For this test, when I used force instead of using pressure, the result was come out. But when I tried with pressure, simulation prompt me that question to use the large displacement simulation. If I chose that, solver failed. If I don't choose, the result comes out but it was not practical. One of the posts I have read on here, they are saying that force and pressure are not difference. What I want to know is if I apply 100N force to face, Is it 100N is total exerted force on the face or on one point only depending on the mesh. If it is 100N is total exerted force on that face, no doubt for pressure and force are not so different. Is there anyone can explain what is the actual difference between force and pressure? Be informed that I clearly understand Force and Pressure in the real world and not only in this FEA.

       

      Thanks.
