Description

Definition of the initial state (deformation, stresses and state variables) on integration point level. This command is used by the solver when writing a state file (impetus_stateX.k and impetus_stateX.bin) for the complete model or for a set of parts (see parameter enid${}_{res}$ in OUTPUT).
