Yes, it really is automatic. In fact, the user spends absolutely no time creating grids for CONVERGE. All of the grid generation is performed internal to the CONVERGE solver (we call this “run-time grid generation”). As a result, highly complicated geometries with moving boundaries are just as easy to set up as simple geometries with stationary boundaries. Great care has been taken to minimize the CPU usage required for run-time grid generation. In fact, this process is so fast that the grid is recreated at the start of each computational time-step when necessary!
