Journal Courant Number

Carl_Para · August 19, 2013, 08:45

Hey,
I'm actually writing a journal file, but recognized that there is no possibility to set a the courant-number for a pressure-based solver, even if i choose the coupled one (which is of course necassary).
On the other side it's no problem to choose the courant number in the fluent grafic window.
Is there any reason for that, or do i have to "activate" the possibility of defining the courant number in this case. For the density based solver it is of course no problem by the way.
Can anyone help me?

Got it, if anyone needs it. But maybe it depends on the fluent-version.

/define/models/solver/pressure-based yes
/solve/set/p-v-coupling 24
/solve/set/p-v-controls [courant-number] [explicit momentum] [explicit pressure]
