How can I specify a temperature-dependent emissivity in Simulation 11.0?


Temperature-dependent emissivity is not supported by the Simulation graphical interface, but it can be specified with a Commands Object like the one below. The database with these commands is attached.


sf,innersurf,rdsf,-999,1 ! Material Set 999 used for temp-dep emissivity
sf,outersurf,rdsf,-999,1

mptemp,1,23,123,223,323 ! Temperatures at which emissivity will be specified
