Hello Rob,

Many thanks for the reply. We have checked the Theory Guide and, effectively, it says that the DO model "is not supported for use with granular (fluid-solid) Eulerian multiphase flows." So our question is now: which ANSYS Fluent radiation models (excepting DO) would be more suitable to determine the radiative heat transfer (mostly infrared radiation but also Sun's radiation) in a gas-solid bed simulated with the Eulerian model?

Again, thank you in advance!
