    Modal stiffness and mass matrices extraction

    Hello to the community! I' m trying to extract the modal stiffness and mass matrices from a real eigenvalues analysis (SOL 103) for an aeroelastic simulation. I've tried to add DMAP alters for the Mhh and Khh matrices, nevertheless I haven't managed to extract them at all. Is there anyone...

    FSI Staggered Simulation

    Hello everyone!!! I would like to perform a staggered FSI simulation in NX NASTRAN. Initially, the aerodynamic loads, obtained via an in-house code, are applied to the FE model in NASTRAN. The linear solver SOL 101 is then used to calculate the displacements. The deformed structure is then used...
