Hello
We're modeling the aluminium casting process by adding layers of discrete thicknesses using the *MODEL CHANGE command and a sequence of *STEP commands. As an example, in step #1, layer #1 is added and then the boundary conditions are applied for five seconds. Then the step ends. In step #2, layer #2 is added (so now layers #1 and #2 are active) and both layers are now being cooled by the boundary conditions for another five seconds. Then the step is ended and layer #3 is added, etc.
Questions:
a)Is their any way to change the step time after it has been defined in the input deck?
OR
b)Is their any way to exit a step before the time is completed, and go onto the next one?
I know one can use USDFLD, etc (pnewdt) to change the time increment, but what about the time step?
Thanks,Andre
