Default UDS derivaties in FLUENT 5.3

Dear All,

If somebody knows how to get access to spatial and time derivatives of FLUENT variables (except of velocities)? or one's own UDS? Where and how these derivatives are defined? Probably, somebody has this experience?

Thanks ,

For the ith UDS the gradient is


where n = 0 is d/dx, n = 1 is d/dy and n= 2 is d/dz

For other variables have a look in mem.h in the apps/Fluent.Inc/fluent5.x folder.

Don't know about time derivatives - if you find out please post.


ps. check back to previous post by Graham Goldin of Fluent - around March 2000.

pss. do you have any experience in writing a DEFINE_UDS_FLUX function - I'm in need of some help since there's no documentation?
