time derivative of velocity
HI,
Is there any way to define time derivative of velocity term in cfx please? I 'm quite interested in this term ,and I want to plot the time history of it. Thanks a lot. Harry 
You should be able to use the '.Time Derivative' operator for most variables in CEL for a transient calculation. For example, for the X component of velocity:
Velocity u.Time Derivative If this doesn't work, then it will almost certainly work with a User Fortran call to USER_GETVAR. C 
I looked for the Time Derivative function but couldn't see it either in Pre or Post. Could you specify where to find it please?
