UDF data access macros for wall fluxes?
In Fluent 20.1, I'm looking for UDF data access macros for the field variables that can be accessed via the GUI in the Wall Fluxes category. I read through the Customization Manual but did not find other access macros than the obvious Face Macros like F_U(f,t), F_T(f,t) etc.
Specifically, I'm interested in radiation fluxes (I'm using the DO-model and solar radiation):
- Absorbed visible solar flux
- Absorbed IR solar flux
- Surface incident radiation
- Radiation Heat Flux
On cfd-online, I found that the Surface incident radiation can be accessed with F_DO_IRRAD_SHELL(f,t,nb) (https://www.cfd-online.com/Forums/fluent-udf/202342-surface-incident-radiation-macro.html). However, I could not find this macro in the documentation or any of the other radiation field variables.
Another question: Surface incident and Incident radiation include does not include the solar radiation, right?
