Example problem 4 is designed to build upon the model and concepts of example problem 3 within a nonlinear convection environment. Convection heat transfer is a function of the media, its flow characteristics, and the geometric relationship of the object to the media. These functions are referred to as configurations. Each configuration is defined to be within a given class of convection correlations. There are presently 31 specific configurations and 6 generic configurations available in Patran Thermal. These configurations are listed in the Patran Thermal User’s Guide Volume 1: Thermal/Hydraulic Analysis. There are two classes of properties used as input for the convective resistors. These are: geometric properties (GP) and material properties (MPID). We will use both forced and natural convection over flat plates for this problem.
