Which software application published by MSC Software has a feature/module called NA_Nonlinear? What is NA_Nonlinear?

The software application published by MSC Software that includes a feature/module called NA_Nonlinear is **Marc**. Marc is a finite element analysis (FEA) software that is designed for advanced nonlinear analysis and is widely used for modeling complex materials and structures under various loading conditions. **NA_Nonlinear** in the context of Marc refers to a module that handles nonlinear analysis capabilities. Nonlinear analysis is crucial in scenarios where materials exhibit nonlinear behavior due to large deformations, plasticity, contact problems, or other complex interactions that cannot be adequately captured by linear assumptions. The NA_Nonlinear module allows users to perform comprehensive simulations involving these nonlinear effects, providing more accurate predictions of a structure's behavior under real-world conditions.
