At the moment I'm writing my bachelor's thesis about a fluid flow problem. My question: Can anybody give a brief explanation about the fact, that if you calculate the same case for different meshes (for a grid study) it needs more iterations to converge the higher the grid resolution respectively the cell number is? Thank you very much in advance!
