Default Real Time Step

Hi !

I have two queries about time steps in FLUENT 5.3 :

1. Does FLUENT do a real time simulation ? i.e. can I get a real time output if I want to capture say what's happening at 1/10000 of a second ?

2. Is it possible to change time steps in FLUENT ? i.e. can I reduce the time step or will FLUENT just go by the CFL criteria ?

1. I think it does, I 've used time step of 1e-8 sec. to simulate the capillary effect under the magnitude of micronmetre.

2. It is possible also, as long as the solution goes divergently.

I'm a newer, but hope these helps

Good luck
