Image 1. The Coupled Eulerian-Lagrangian (CEL) adaptive mesh refinement enhancement for Abaqus 6.12 improves performance in models in which large deformation exists, such as airbag deployment, by automatically refining the mesh as needed in Abaqus.
Image 2. In Abaqus 6.12, wedge elements can be generated along selected boundaries of a part or a cell, and the interior filled with tetrahedral elements. Adding layers of small elements along the walls improves the analysis of boundary effects in fluid flow and heat transfer analyses.
Image 3. Mesh parts can now be converted into geometry with Abaqus 6.12. This enhancement is useful for creating geometry from deformed meshes (e.g., a stent), creating an interior acoustic cavity inside of a vehicle, as well as a number of other industry applications.
