200 Celsius and 50 bar (5 MPa) pressure. The material is 316L. According to the 2014 SolidWorks static simulation (even 2015 SW) the 4 mm wall thickness is not enough. That is not correct. According to the classic calculation is enough. The simulation setting was Large displacement, but other settings had the same result. I am helpless what did i wrong that i can't get result in harmony with the calculation. Do you have any idea?
Try with a small meshing configuration.
I changed it 0.5 mm size, and 8 is the number of elements in a circle. Abit better the result but beyond the yield strength.
