Hey, recently i created a model of a composite propeller blade using NX software (CAD model, FEM, added material properties and pretty much everything). After that i exported it as a .bdf file to open in MSC Patran. The goal in the Patran was to define boundary conditions such as contact between a projectile and the propeller blade, velocity of the projectile and contact between them. I have been working on project with projectile contact for a while and I am pretty sure that everything i set up in PATRAN is right, however I am getting bunch of errors, whn it comes to solving this experiment in MSC Dytran and honestly I am pretty lost... If someone knows how to fix those problems, let me know. You would be a life saver.
