I am currently working on the sensitivity analysis on the meshes and time steps. However, I have a question on the convergence criteria. According to the Ansys training notes, we need to set the convergence criteria of minimum of 1e-4, if we need it to be more accurate, we have to reduce it. The question is, for my application, it is enough to set it at 1e-4? If it is not enough, which value should I set and how to decide which value is the most suitable value?

Is it correct that we should set the default value first (1e-4) and after getting the best mesh and time step, run this setting and compare results with my experiment results? If the results tally, then the convergence criteria set was ok, if it does not tally, then I should reduce the convergence criteria till I get the best results. Does that make sense?
