as serezhkin write it's working.Thanks!
But keep in mind that the properties will work only reffered to the Coord 0.

Here, the thermal conductivity has been defined in x,y and z direction, respectively. But why again thermal conductivity is defined in # statement? Is it average thermal conductivity? If so average is 168.33 [W m^-1 K^-1] and not 175 175 [W m^-1 K^-1].
I am facing same issue, in which I have use a solid material in cfx which is an-isotropic considering varying thermal conductivity in x,y,z.
To quote #11
" THERMAL CONDUCTIVITY:
Option = Orthotropic Cartesian Components
Thermal Conductivity X Component = 0.001 [W m^-1 K^-1]
Thermal Conductivity Y Component = 500 [W m^-1 K^-1]
Thermal Conductivity Z Component = 5 [W m^-1 K^-1]
#Thermal Conductivity = 175 [W m^-1 K^-1] "

As this is an undocumented feature I don't think anybody will know the answer to your question. Unless you have access to the CFX source code.....
So the only way to find out is to test to see what it does. Do a simple demonstration simulation using anisotropic thermal conductivity, and then repeat it using 10x the isotropic thermal conductivity and see if it makes any difference. The isotropic thermal conductivity may well be ignored by the solver but it is required so the check for the necessary parameters to define the run are present. But that is just a guess.
