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!
