Unconvergent results in transient structural

      Hi everybody, i have a technical problem in my simulation. I analyse a 2D planar body in which i want to get the maximum stress.

      My calculation is not unconvergent, the calculation actually works very well. The problem is the following

      I noticed that by increasing the mesh refinement of the planar element i get always different results. In the following plots you can see on the x-axis the number of the element on a certain edge of the structure, while on the y-axis there is the maximum stress during the simulation.

      Hi, if the probe is at area (e.g., sharp corner) prone to stress singularity, you won't see stress results converge in terms of mesh size. You can either modify the sharp corner with a fillet or probe results at least one element away from stress singularity area.n
