Hello CFD Online members. I haven't been using CFX for a while so some of my memory about it already faded.

As I recalled, one could have Density Gradient and Pressure Gradient as additional variables to be post-process in CFD-Post (without using CEL), but I couldn't find it during post-processing, so I figured that I might've missed something.

I have a very faint memory that I have exported density gradient plots once by changing selected variables in Output Control, but this time I couldn't find it.

Was I looking in the right place? Anyway, how can I tell CFX to have Density Gradient and Pressure Gradient as a variable among the outputs?

Thanks in advance

One way is to compute the gradient in cfd-post:
Variables tab, right click - New
method:gradient
gradient of: density
