I have a problem: I want to make a simulation about a dished end. I made it with PVelit, and it's okay. But i need to make it in FEA(i choose SW), but the solution show too much stress. Why does it?
The pressure is 10 MPa, the temperature is 100°C, and the wall is s=20 mm. It should be under 203 MPa! Please help me somebody! Thank you!
