User subroutine to define nonuniform distributed flux in a heat transfer or mass diffusion analysis.

User subroutine DFLUX:

  • can be used to define a nonuniform distributed flux as a function of position, time, temperature, element number, integration point number, etc. in a heat transfer or mass diffusion analysis;

  • will be called at each flux integration point for each element-based or surface-based (heat transfer only) nonuniform distributed flux definition in the analysis;

  • ignores any amplitude references that may appear with the associated nonuniform distributed flux definition; and

  • uses the nodes as flux integration points for first-order heat transfer, first-order coupled temperature-displacement, first-order coupled thermal-electrical-structural, and mass diffusion elements.
