Modeling Extreme Deformation and Fluid Flow with Abaqus
Abaqus includes several advanced techniques for modeling extreme deformation and fluid flow. The pure Eulerian analysis capability in Abaqus/Explicit allows for effective modeling of fluid flows and extremely large deformations in solids. Coupling the power of this capability with the traditional Lagrangian approach makes it possible to simulate complicated multiphysics phenomena such as fluid-structure interactions where highly deformable materials interact with relatively stiff bodies. The need for modeling high-velocity impacts, extremely violent fluid flows, and material phase changes requires the use of Smoothed Particle Hydrodynamics, a meshless Lagrangian method capable of solving these challenging problems efficiently. This course aims at providing users with a solid understanding of the Coupled Eulerian-Lagrangian (CEL) and Smoothed Particle Hydrodynamic (SPH) methods and illustrating approaches to setting-up and analyzing real world problems using these advanced analysis methods.
