Version 70.5 of MSC/NASTRAN can simulate larger problems with less resources and speeds data recovery. Performance improvements and new reordering algorithms have been added to both direct and iterative solvers, reducing required disk space, memory, and CPU time. MSC reports that for some large problems, CPU time has been cut in half. Also new are a generic control system technology for all existing aerodynamic methodologies that allows for a more accurate simulation of vehicle control system behavior during flight, and a geometric and nonlinear damping feature to help automotive engineers better design suspensions. In addition, MSC has made its user messages available for customization. Commonly encountered error messages can be modified to provide site-specific information such as hints, tips, and work-arounds.
