Hi, Everyone
DEM Time Loop, as shown in the graph posted below, is implemented in the subroutine named DES_TIME_STEP. As this flow chart shows, updating DEM variables is finished after calling the subroutine usr1_des. But i do not find that particle size, which, in my point of view, is one of DEM variables, is updated in this subroutine. So, could you please tell me where it is updated?
