Nonlinear Transient Analysis

Nonlinear Small Displacement Transient and Nonlinear Large Displacement Transient (LGDISP) Analyses are currently available to solve nonlinear problems which include transient effects.

The predominant difference between Nonlinear Quasi-static Analysis and Nonlinear Transient Analysis is the inclusion of Inertia and Momentum terms in the solution of the Energy equation. This nonlinear transient solution sequence typically supports all nonlinear features supported by NLSTAT, including Geometric Nonlinearity, Material Nonlinearity, and Contact. Subcase continuation between nonlinear transient and NLSTAT is also supported.
