Almost any severe application can benefit from the embedded deep physics in our explicit suite. With ANSYS explicit dynamics products, you get a comprehensive set of advanced tools to help gain insight into virtually any event that can be simulated. For example, the FE (Lagrange) solver is the most commonly used and the computationally fastest method to represent structures. It is best suited for tracking shock waves and peak pressures. Within each element, Lagrange captures the material location of the discretized model and follows its deformation as forces are applied, resulting in distorted elements. The Euler method follows the flow of materials throughout a region represented by a fixed mesh. It is ideal for modeling severe deformations of solids as well as the flow of liquids and gases. With the ANSYS virtual Euler solver, the mesh is generated automatically without any user input. Arbitrary Lagrange–Euler (ALE) combines the advantages of Lagrange and Euler while eliminating some of their shortcomings. It is ideal for simulating materials with severe deformations in which high-resolution shock response is desirable. Smooth particle hydrodynamics (SPH) is a mesh- free method best suited for problems involving material separation, such as hypervelocity impacts or crack propagation in brittle materials. You can combine Lagrange, Euler, ALE and SPH in a single problem to produce the most efficient and highest accuracy results possible. "The ability to couple Eulerian and Lagrangian frames of reference is especially helpful in blast field modeling. With ANSYS explicit dynamics, energy is easily transferred between the two for accurate modeling of the entire blast process." Dale Preece Global Technology Development Orica USA Inc.
