        solids have artificially high thermal conductivity
      hotter solid       temperature = Th    emissivity = eph
   // 0.01 m thick////////////////////////////////////////////////


      non-participating medium, 1 m thick



      colder solid       temperature = Tc    emissivity = epc
   // 0.01 m thick //////////////////////////////////////////////
   
Exact solution: Qr = (Eh - Ec)/(1/eph + 1/epc - 1) where Eh and Ec are the emissive powers ( E = S*T**4 ) S is the Stefan-Boltzman constant. Values: Th = 800K, Tc = 400K, eph = 0.3, epc = 0.1 Confirmation or modification of these settings will be requested. The macro r193 is loaded to set emissivity via a 3D store, and to activate line-printer plots. It is necessary to store PRPS so that the LTLS solver knows which cells contain solids, and therefore computes the correct WGAP.
