Grid convergence for unstructured meshes
Hi everyone,
I am trying to streamline the mesh independence study with 3 different mesh size using Grid Convergence Index and Richardson Extrapolation. I set the grid refinement ratio(r) to 1.4. My question is; as we use unstructured mesh, I am not sure about the value of the local element size. Should we apply this value(r) only for Initial Mesh at the beginning and keep the other parameters same? Is it also necessary to change the refinement values on the surfaces and curves? Thanks |
