Load case

A load case object collects all boundary conditions, Dirichlet and Neumann constraints, which define the current problem. A load case block is linked directly into an analysis object. Each Neumann block is separately weighted by a factor FAC.

The example below shows a load case including a nodal load block, one element load, and one set of Dirichlet conditions. Activated Dirichlet sets can also (partly) be deactivated.

LD-COM 1
 TYPE = LD-NODE 1    FAC=1.0
 TYPE = LD-ELEM 1    FAC=1.0
 TYPE = BC-DIRICHLET 1
 TYPE = DEACT-BC-DIRICHLET 2     !only for special applications needed

Note that DesignBoundaries for supports do not have to be added to the load case.
