I have a problem with CFX 11.0. I'm trying to figure out various ways of applying volumetric heating. My problem:

I have a beam of ions hitting water, and causing heating (Brag peaking, etc.). MCNPX made some text files relating radius and depth to the amount of heat generated in the water. So now I have Q_dot(R,Z).

My model is in cylindrical coordinates, but when I go to import the data file (user function), I can either have one dimensional or 3 dimensional and the 3 dimensional is in x,y,z which poses a problem (since its a function of 2 variables). How should I go about taking this data and revolving it around the axis? My next test will try and put the data in an expression form. Thanks in advance!

Problem solved. A little elbow grease and some sleepless nights created a massive text file across varied theta angles which imports easily into CFX....

Now if only I could graph that particular function in CFX...

Dear Wooster,

You are asking in the wrong Forum.. It may take longer to get a response from CFX-only readers.

In anycase, create an Algebraic Additional Variable and make it equal to your interpolation function.. You will see it in CFX-Post..

Insert Additional Variable, select Undefined.

Goto your Domain, and under Fluid Models/Solid Models activate your additional variable for this domain. Set it equal to your function.. Done..

Thanks Opaque, I've implemented your suggestion. also, I put a similar question to the CFX only forums as this one was obviously filed wrong (on my part).
