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 to recalculate the aerodynamic loads and obtain new displacements. This aeroelastic cycle will be repeated until displacements and loads converge. My question is if there is a way in NASTRAN to include the prestress state incurred by the previous aeroelastic cycle. Can it be done via a restart analysis or is a more sophisticated solver needed? Thanks in advance!
