Structure for the Material_Group tuple = ("Material Name", "Value"). The "Value" must be a JSON String dictionary.

If no Material_Group is specified, a default material of "Catalytic" with emissity of "0.8" is applied to all capsGroups.

Material Group JSON String Dictionary

For the JSON string "Value" dictionary (e.g. "Value" = {"surfaceType": 1, "emissivity": 0.8}) the following keywords ( = default values) may be used:

• surfaceType
  The surface type must be a string integer, e.g. "0" or "10,
  or a case insensitive partial match to one of:
  • "Non Catalytic"
    
  • "Fully Catalytic"
    
  • "RCG"
    
  • "TUFI"
    
  • "ORCC Coated ACC"
    
  • "PCC Coated NEXTEL 440"
    
  • "RLV Design Goal"
    
  • "SIRCA"
    
  • "TABI"
    
  • "Grey C-9 Coated NEXTEL 440"
    
  • "SiC – SiC"
    
  • "C-CAT"
    
  • "LVP Coated ACC"
    
  • "SiC Coated Carbon – Russian"
    
  • "INCONEL 617 PreOxidized"
    
  • "Mars Fully Catalytic, No O2 Recombination"
    
  • "Venus Fully Catalytic, No CO Oxidation"
    

• emissivity
  Emissivity of the material [0 - 1]

• groupName = "(no default)"
  Single or list of capsGroup names on which to apply the material (e.g. "Name1" or ["Name1","Name2",...]).
