anisotropic material in CFX 14

marcoymarc · May 28, 2013, 13:46

Hi everybody.
As title suggests, i need to set different thermal conductivity over x,y,z.
I tried to edit in command editor and set something like:

THERMAL CONDUCTIVITY:
Option = Orthotropic Cartesian Components
Thermal Conductivity X Component = 29 [W m^-1 K^-1]
Thermal Conductivity Y Component = 29 [W m^-1 K^-1]
Thermal Conductivity Z Component = 10 [W m^-1 K^-1]
END

but it doesn't work.

Anyone knows how to fix this?
Thank you in advance!

What version of CFX are you using?

Oh - just saw you are on V14. This looks OK to me, but getting non-documented CCL correct is always tricky. Have a look in the <CFX-ROOT>/etc/RULES file and see if you can work out the correct syntax for these statements. What you have written looks OK to me so I cannot spot the error.

1. The Material Group for this kind of material must be "User".
2. This material definition don't use in CFX-Pre. Write CCL file and append this with solution in Solver Manager
