The industry standard for over 50 years, Simcenter™ Nastran software from Siemens Digital Industries Software is a premier finite element method (FEM) solver for computational performance, accuracy and reliability. It is a powerful solution for linear and nonlinear structural analysis, structural dynamics, acoustics, rotor dynamics, thermal analysis, aeroelasticity, and optimization. Engineers greatly simplify the modeling process by using the same file formats for all solution types. Available as an integrated solution within Simcenter 3D, or as a standalone solver, Simcenter Nastran gives the flexibility to deploy to the computing systems that will best serve users' application needs.
