MSC Actran 2024.1 Win/Linux
Actran 2024.1 includes new acoustic, vibro-acoustic and aero-acoustic technologies with a focus on creating better models faster.. Release Highlights Some main highlights of this release include the following: Compressed Reduced Impedance Matrices (CRIM) for Nastran PEM and Actran for Trimmed Body analyses (2024.1) We introduce a new compressed way to store reduced impedance matrices (RIM) for 3D acoustic trim analysis. The uncompressed matrices, stored in modal coordinates, can be very large for models with lots of modes, requiring a large amount of disk space and I/O operations. Starting from Actran 2024.1, users can specify a CRIM_MODE datablock in the trim model, defining if they want to compress structure and/or fluid modes, and the compression tolerance. Activating this option, the RIM...
