Access Solid Material Properties using UDF

How to access solid material properties of a porous equilibrium zone in an Ansys Fluent User-Defined Function (UDF)?

For the thermal equilibrium porous model Ansys Fluent doesn’t create an additional zone for the porous solid. Therefore, you cannot access material properties with the usual C_* macros. If you need access to the material properties of the solid zone, you can access the data structure directly. It is only available for compiled UDFs and cannot be used when interpreting.

The attached document explains this method in detail.

Important

Whenever you access the data structure, keep in mind that this can change without prior notice. Changes will not be documented in the release notes or the migration manual. If your UDF relies on macros that are not documented in the Ansys Fluent Customization Manual, Ansys can decline providing technical support. If you observe unusual behavior, reproduce the behavior without using undocumented macros before contacting the Ansys technical support.
