Engineering FEA Software Products

NEi Nastran finite element analysis (FEA) stress simulation software, along with Femap, reduce product development costs and improve time-to-market. Simulate real-world structural, thermal, fluid-flow, and aero-elastic behavior of both simple and complex 3D product designs, including composites. Model generation and analysis time is reduced by combining powerful and easy-to-use finite element modelers with extremely fast analysis solvers that have a proven record of accurate results.
