Transient Simulation: Initial Time -- CFD Online Discussion Forums

April 18, 2010, 09:19	Transient Simulation: Initial Time	#1
blackbody Member Join Date: Feb 2010 Posts: 33 Rep Power: 16	Hi everyone! Quick question: I want to simulate a transient rotor/stator behaviour: first i created the frozen rotor solution. than I specified some monitor points to check if the result gets "periodic, steady" over time and therefore has converged. this has used about 400 timesteps. in this time, the rotor has rotated over 4.5 pitches. now i want to run the transient simulation with an output of transient results (for each time step). can i specify the initial time to 0s (rotor is at beginning place) and use the old result i got as an initial value? will the convergence be still there??? thank you!
