Lernziele
This course will cover the capabilities available in NX Nastran SOL 601 and 701. It will consist of both lectures and hands-on workshop sessions. NX will be used as the pre- and post-processor for the workshop sessions. Participants will learn the best practices to handle large problems and resolve convergence difficulties.
