Initial Conditions

The nodal initial values are generated by isoparametric generation in a way similar to that used to generate nodal coordinates. Terminate each initial condition with a blank card. In case of dynamic analysis, three I.Cs are expected if IREADR.EQ.0. Terminate the generation of each one with a blank card. In case of static analysis, no I.Cs are expected unless you set the flag IWRITR to one. In this case, initial velocity and initial acceleration are expected to be written to the restart file. DYNAZ will compute and write the initial displacement. The initial conditions overrides the first value of the load time function and causes the load time function to be shifted parallel to itself. In case of velocity and acceleration control, The boundary initial conditions will be used to evaluate the integration constant.
