DEFINITION
IHTCOF specifies the heat transfer coefficient at the interface between two objects.
REMARKS
The interface heat coefficient may be specified as a constant, a function of time, or a function of interface pressure. If Ftype = 0, use the operand HeatCoeff. If Ftype = 2 or 3, use the operands Ndata, Time/Press, HeatCoeff(i). When Ftype = 2, each data pair should be provided on a separate line, resulting in Ndata lines of Time/Press(i), HeatCoeff(i). The interface heat transfer coefficient is generally a complex function determined by the interface pressure, amount of sliding, and interface temperature.
