Advanced Numerical Methods for Nonlinear Problems

With a solid foundation of element and material technology, ANSYS structural mechanics offers various advanced modeling methods for different kinds of applications. There are modal, harmonic, spectrum, rotordynamics, flexible multibody dynamics, component mode synthesis, cyclic symmetry, delamination, composite failure, fracture mechanics, adaptive meshing, 2-D rezoning, submodeling, substructuring, element birth and death, and topology optimization, among others.

In addition, ANSYS structural mechanics offers advanced capabilities that allow users to simulate a variety of physics phenomena, such as thermal–stress, electromechanical, structural–acoustics, mass diffusion and simple thermal–fluid analysis.
