DLOAD

User subroutine to specify nonuniform distributed loads.

User subroutine DLOAD:

  • can be used to define the variation of the distributed load magnitude as a function of position, time, element number, load integration point number, etc.;

  • will be called at each load integration point for each element-based or surface-based nonuniform distributed load definition during stress analysis;

  • will be called at each stiffness integration point for computing the effective axial force, ESF1, for pipe elements subjected to nonuniform load types PENU and PINU;

  • cannot be used in mode-based procedures to describe the time variation of the load; and

  • ignores any amplitude references that may appear with the associated step definition or nonuniform distributed load definition.
