User field function for specific heat definition

Hello,
I am defining features of my computation through user coded functions. I have defined viscosity or conductivity for example, via external user code, which, while loaded, create different user field functions. In the physic countinua, I then choose 'field function' for the method to solve the properties. I wish to do the same for the specific heat, but it seems not possible to do so, as it is not possible to select the method 'field function' for this parameter (only the options 'constant' and 'polynomial' are available, and 'field function' becomes available only when EOS compressible is on, which is not for my case). I am wondering if I really get it well, or if there is a way to user define the specific heat in ccm+,as it was possible to do so in starcd. Thank you for any advice.

the field function can only be used for dynamic viscosity, thermal conductivity and turbulent prandtl number. For density and specific heat, these two properties can be defined as the polynomial

Hello Htwana
Thanks for your notification, which confirms what I have understood so far, i.e that specific heat can't be defined through a user function. |
