gradients of passive scalars
 

Hi everybody!

I am working with user subroutines and defined some passive scalars in my domain. My problem is that I need to set up functions for those scalars which include their gradients in respect of spatial distribution. How can I get the gradient of a passive scalar in a certain cell?

Thanks for any help in advance!

With the the "operate" command you have the possibility to calculate a gradient of a cset.

e.g. GUI version. Main ProStar menu -> Lists -> Post-Registers. Buttom operate... > Funtion -> Multi-Register -> Gradient.
