User subroutine to specify nonuniform distributed loads.

User subroutine VDLOAD:

  • can be used to define the variation of the distributed load magnitude as a function of position, time, velocity, etc. for a group of points, each of which appears in an element-based or surface-based nonuniform load definition;

  • will be called for load integration points associated with each nonuniform load definition including PENU and PINU loads applicable for pipe elements;

  • does not make available the current value of the nonuniform distributed loads for file output purposes; and

  • recognizes an amplitude reference (Amplitude Curves) if it appears with the associated nonuniform load definition.
