Towards interactive steering, visualization and animation of unsteady finite element simulations

Progress towards interactive steering of the time-accurate, unsteady finite-element simulation program DYNA3D is reported. Rudimentary steering has been demonstrated in a distributed computational environment encompassing a supercomputer, multiple graphics workstations, and a single frame animation recorder. The coroutine facility of AVS (application visualization system from AVS Inc.) and software produced in-house has been coordinated to prove the concept. This work also applies to other large batch-oriented FORTRAN simulations ("dusty decks") presently in production use.<<ETX>>
