Summary: Control solution stability of radiation analyses.
Flag
Max_Pseudo_Time_Step_Size A
A = the maximum allowable time step size
Description
If the temperature solution changes too rapidly in a radiation analysis, you can control the solution by specifying a maximum pseudo time step size. This effectively reduces how much the temperature can change from one iteration to the next by limiting the time increment of each iteration.
Autodesk Simulation CFD writes out the fluid time step size and the thermal time step size to the ".sol" file.
