NX Nastran for Femap - Superelements

Despite the ever-increasing power of computers, finite element models are continuing to get larger, which means that finite element analysis (FEA) solutions can require hours of compute time. NX Nastran® software solves large systems of equations efficiently using sparse matrix algorithms; however, NX Nastran – Superelements offers still greater efficiency. Superelements, an add-on to NX Nastran – Basic, plays a key role when solving very large and complex finite element models by decomposing larger structures into equivalent sets of smaller substructures called superelements. NX Nastran – Superelements can be used with all NX Nastran analysis capabilities; is particularly efficient in large, full-system analysis such as an entire aircraft, vehicle or ship; and performs incremental and partial assembly solutions.

Benefits

• Accelerate innovation through enhanced solution efficiency
• Reduce product design risk through the ability to perform more iterations
• Enable enterprise-wide collaboration by combining models from different sources (internal and external) and masking proprietary data
• Maximize output of precious computing resources; reduce the amount of memory and disk space required
