Ansys Explicit Dynamics is a transient explicit dynamics system in Mechanical that can perform a variety of engineering simulations, including the modeling of nonlinear dynamic behavior of solids, fluids, gases and their interaction. Additionally, the LS-DYNA system in Mechanical is available to analyze a model using the LS-DYNA solver.

A typical simulation consists of setting up the model, interactions and the applied loads, solving the model's nonlinear dynamic response over time for the loads and interactions, then examining the details of the response with a variety of available tools.

The Explicit Dynamics application has objects arranged in a tree structure that guide you through the different steps of a simulation. By expanding the objects, you expose the details associated with the object, and you can use the corresponding tools and specification tables to perform that part of the simulation. Objects are used, for example, to define environmental conditions such as contact surfaces and loadings, and to define the types of results you want to have available for review.

The following sections describe in detail how to use the Explicit Dynamics application to set up and run a simulation:
