A sample Nastran deck showing the changes to a SOL 103 for the truck-with-container
to export the characteristic matrices is shown in Figure
18. (The full Nastran files are available as truck_wload_irke_tam_out.dat
and truck_irke_tam_out.dat.) This deck uses standard Nastran cards
to write out the candidate set TAM mass and stiffness matrix to the punch
file in DMIG format. The punch files resulting from these two Nastran
solutions are provided so the user can quickly navigate and experiment
with the Genetic Algorithm.
