Hello,

I am working on a radiative heat transfer problem, and it is necessary to define the absorption coefficient around the field. I have noticed that the "cs_user_radiative_transfer.c" file in the example folder, and I am quite confused that the formal parameters of the "cs_user_rad_transfer_absorption" function does not include the temperature.

So I am very eager to find out how to call the temperature of each cell (which I defined in the GUI, thermal option).
In the .C file, it is easy to call the ID and coordinate of each cell by the struct "cs_glob_mesh_quantities" and "cs_glob_mesh", should I consider the similar method to achieve my goal?
And last, the .C file have a step of reading from file, declaring arrays with 78 dimensions, this makes me confused too.

Thanks for your generous help.

Hello,

You can always access the temperature using the field API, for example:
In which case you then have access to current temperature values in the cvar_t array.

I am not sure which arrays with 78 dimensions you are referring to.

Greeting,

First, I really appreciate it.
And the arrays I mentioned which have 78 elements are these below They initially appeared in the example code named "cs_user_radiative_transfer.c" in the folder, "user_examples", or in the attachment file.

Thank you so much!

Hello,

These arrays are related to a data file for a specific (atmospheric radiation) case, so you can ignore them.

Hello,

Thank you for your patience. It really helps a lot.
