DEFINITION
LOCTMP specifies the local heat transfer boundary definition for an object. The keyword should be used if the local heat transfer is specified.
REMARKS
The keyword defines the heat exchange information such as temperature, convection coefficient, and the radiation view factor for a specific boundary. If the data is of constant type, only the constant value is given in the data list. If tabular data is used to describe any of the above variables, the number of data sets is listed followed by the data set. The following example shows how environmental temperature, emissivity and heat flux are constant and the convection coefficient is a function of temperature. Note the use of comments on the keyword describing the contents.

The value has higher priority than the interface heat transfer coefficient defined in inter-object data (IHTCOF).
