• If empid is zero and epsilon is one, then no emissivity resistor is made and the surface node will serve as the radiosity node for any radiosity resistors to be made.

• If empid is zero and epsilon is greater than zero but less than one, then a radiosity node will be created and joined to the surface node with a Patran Thermal subtype 5 resistor.

• If empid is not zero and epsilon is zero, then a radiosity node will be created and joined to the surface node with a Patran Thermal subtype 1 resistor.

• If Viewfactor detects a zero valued resistor, then that resistor will not be made and the surface node will serve as the radiosity node.
