User subroutine to specify prescribed boundary conditions.

User subroutine VDISP:

  • can be used to prescribe translational and rotational boundary conditions;

  • is called for all degrees of freedom listed in the associated boundary condition;

  • allows user to specify values for either the degree of freedom or its time derivatives such as velocity and acceleration;

  • releases the boundary condition by default if the user does not specify a value for the boundary condition;

  • can be used to apply a concentrated load, instead, by adjusting the default motion of the node;

  • can be called for blocks of nodes for which the boundary conditions are defined in the subroutine.
