I have a very basic question… Why do we use uniform grids for all the problems unlike conventional CFD where we use non-uniform grids. I saw couple of papers on non-uniform grids (using Jacobian) for LBM but I don’t think most of them prefer to use curvilinear co-ordinates in LBM. Is there any specific reason behind this.
Anybody please answer this question. Lot of people in my school are asking this question.
Thanks and Regards,
