I should impose variable time stepping that would works like follow:
if(flow_time <= 0.15) { (timestep = 0.001); } else if(flow_time > 0.15 && flow_time <= 0.3) { (timestep = 0.0005); } but I do not know which is the correct way to do that using DEFINE(I have used UDF for velocity inlet and pressure but never for time stepping) thank you in advance |
