Vidushi is on a distinguished road
Hi everyone,

Does anyone know what all information is stored in the data structure for storing reaction variables for writing a UDF, the pointer to which looks like Reaction *r? Does anyone know where I can find the definition of this data structure?

Thanks in advance.

vinerm will become famous soon enough
All such structures are stored in header files that are installed with Fluent's installation. The one you are looking for exists in materials.h. All the header files are located at


material.h is in .../src/material/

PM to be used if and only if you do not want something to be shared publicly. PM is considered to be of the least priority.
