Analysis software Abaqus/Explicit

simulationmodelingpost-processing

Overview
Abaqus/Explicit is an explicit-dynamic finite-element solver designed to simulate short-duration, highly nonlinear transient events such as drop tests, automotive crashes and ballistic impacts. It is also applied to many quasi-static processes where robust handling of nonlinearity, contact and large deformations is required. Abaqus/CAE supports pre- and post-processing for Abaqus/Explicit and the product is engineered for production use with emphasis on usability and efficiency.
