Radiation
 

Hi all,

I have a quite complex geometry which consists mainly of two parallel plates, partially filled with porous media and a gas flow through it. My calculation is transient with transient inflow boundary condition with steps and ramps, and I'm solving mass and heat transfer. In the region without porous media I want to regard radiation. My problem is, that if I have defined the inflow with steps, the calculation performs well, but not with a ramp. Star gives me the error:

*** ERROR #057 *** HEAT TRANSFER BOUNDARY TYPES OTHER THAN CONDUCTION NOT AVAILABLE AT SOLID-FLUID INTERFACE; EXECUTION STOPPED

I only defined conduction, that's not the problem. Does anybody know this case?

Thanks, Nicola
