Moving Reference Frame (MRF) with UDF -- CFD Online Discussion Forums

April 14, 2011, 15:18	Moving Reference Frame (MRF) with UDF	#1
Tobard New Member Join Date: Mar 2011 Posts: 28 Rep Power: 15	Hello everybody! I need to do a transient simulation of a rotating shape. I want to use a profile law to control rotational speed. My geometry is not axisymmetric so I cannot use properly moving wall conditions. Does anyone know if it's possible to use a User Defined Function (UDF) with a Moving Reference Frame? I don't see any available field to hook my UDF... is there however a way to make rotational speed change during simulation? Thank you very much! Tobard
