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® CFD writes out the fluid time step size and the thermal time step size to the ".sol" file.
