User-Defined Heat Transfer Properties

The LOADLIB I/O Option Entry, can be used in combination with:
  1. The QVOL and QVOLLIB Bulk Data Entries for the definition of time-dependent and temperature-dependent volumetric heat generation through user-defined external functions, and/or,
  2. The PCONV and PCONVLIB Bulk Data Entries for the definition of time-dependent and temperature-dependent free-convection coefficient through user-defined external functions.
  3. The QBDY1 and QBDYLIB Bulk Data Entries for the definition of time-dependent and temperature-dependent uniform heat flux through user-defined external functions.
  4. The SPCD and SPCDLIB Bulk Data Entries for the definition of time-dependent and temperature-dependent uniform heat flux through user-defined external functions.

The external functions may be written in Fortran or C. The resulting libraries and files should be accessible by OptiStruct regardless of the coding language, provided that consistent function prototyping is respected, and adequate compiling and linking options are used.
