Nodal Load Vector or Prescribed Kinematic Condition

DYNAZ uses the boundary condition code to recognizes whether the values assigned to a specific degree of freedom is load or prescribed boundary condition. If the DOF is not active, then the reaction is computed. The nodal values are generated by isoparametric generation in a way similar to that used to generate nodal coordinates. Terminate each load vector with a blank card. The final value at the node is computed according to the following equation

\begin{displaymath}F({\bf x},t) = \sum_{i=1}^{\mbox{NLVECT}} p_i({\bf x}) G_i(t)

where pi is load vector number i and Gi is load time function number i.
