thank you! that was counter intuitive! Another follow up question (sorry for the spam!)
Is there a way to specify a set of abosrption coefficients (AC) for a given temperature? Or in other words, a gray model for a specific temperature? My sim has temperautres between 5-15 kK and the AC is are different for a given constant temperature, as seen from the bottom 2 screen shots below (from http://dx.doi.org/10.1615/HighTempMatProc.v10.i1.50). If a UDF is the only way to achieve this, where do you recommend that I start in the UDF manual? thank you again!
