I am simulating a pressure vessel subject to internal pressure using 3d elements.
The cylinder is 10 mm thick, has an internal radius of 700 mm and a length of 1000 mm.
My goal is to have at least 2 elements on the radial direction to catch the bending stress and to increase the element size on axial and circonferential directions to avoid excessive number of elements.
Can you help me?
Thank you in advance.
