The Abaqus Unified FEA product suite has always offered significant capabilities that are used to solve multiphysics problems. These capabilities have been developed over many years and are fully integrated as core Abaqus functionality. In this presentation, we will discuss two of these capabilities that are embedded in 3DEXPERIENCE Abaqus/Explicit: Coupled Eulerian-Lagrangian (CEL) and Smooth Particle Hydrodynamics (SPH). CEL and SPH are well-established methodologies that have been broadly applied to problems of extreme deformation of materials in any phase (solid, liquid, or gas), including materials as they transition between phases (such as in the melting of metals. CEL and SPH capabilities in Abaqus/Explicit are demonstrated using industrial examples, as well as the setup of CEL to solve a benchmark UNDEX problem using Abaqus/CAE and SPH to solve a dynamic fluid flow problem on the 3DEXPERIENCE Cloud platform.
