Hello All,

I am doing some Static analysis to analyse a container structure that subjected to internal pressure. the picture below shows a stress around hole. The stress was 130MPa with fine mesh and 1.1 element growth size. To investigate if it is singularity or not, I applied many mesh control size on the hole and the stress value kept getting higher and higher. 130 MPa to 170 MPa to 233MPa to 265
