UDF for time steps -- CFD Online Discussion Forums

August 14, 2007, 12:54	UDF for time steps	#1
David Guest Posts: n/a	Hi folks, I am using Fluent to simulate the mass transport in a rotating flow, and have a couple of questions on time steps. (1) How to decide the initial time steps? (2) How's the computational accuracy of UDF controlling time steps? I need to simulate large times and small uniform time steps (eg t=0.1s) take really long time. Thanks in advance for your reply.
