Transient CHT

Hello All,
I am working on a Transient CHT analysis problem. In which the flow enters in to a big cavity at a Mach number of 0.2. due to the large area the velocity looses its magnitude and the maximum velocity inside the cavity worked out to be 2 to 5 m/s. There are 2 fluid domains and 4 solid domains. the simulation (change in BCs every 300 Secs) need to be performed for 1800 Secs (using a time step of 0.5 sec currently). Node count of the TET mesh is 0.22 Million (1 element extruded mesh). the solving time for one outer loop iteration worked out to be 5 Mins. Based on this the total time required to complete 1800 secs seems to end up in weeks. Could anybody help me out in a way so that the transient simulaiton time can be reduced considerably. Thanks in Advance |
