User-defined Time Step
 

Hi all,
I would like to define a user-defined time step with the DELTAT UDF
The UDF is defined this way:
DELTAT(name, d)

Domain *d: pointer to the domain over with the time stepping control fonction is to be applied.

I need my time step to be depend on the angular velocity of my body Cg which is in rotation. I can't get the angular velocity with the DT_OMEGA_CG(dt) beacuse dt isn't declared in DELTAT so I don't know how to do.
Does anyone would have an idea?
Thanks!

Hmm, In which software are you trying to do this. If it's fluent you can repost your query in the Fluent section of the forum.

Yes, I am using Fluent. Thanks for the advise.
