Hi guys,

I am normally a Fluent user, but an trying to do some quick post processing in CFD/CFX Post, and was wondering if any of the dyed in the wool CFX users could give me a quick helping hand?

I want to post process some data which i have not exported from my Fluent case file, but cannot seem to get CFD Post to recognise my CEL expression.

I was wondering if this was because CEL mathematical expressions are not recognised in CFD post, or perhaps my syntax is wrong? Can anyone help?

the expression is basically:

1.004*loge(Temperature)@X3-0.287*loge(Pressure)@X3

where X3 is a user created sampling plane.

As you can see, basically, I am trying to check the entropy generation calculation from my solver, but for some reason the expression is not accepted in CFD Post...

Any help from you CFX guys would be much appreciated,
best regards
Jon
