This tutorial demonstrates how to partition a 3D part to create a swept mesh. The example explores different strategies for partitioning the geometry, and demonstrates how to combine hexahedral and tetrahedral meshes. Suggestion de Produits.If the fluid body is bigger than the piston rings, Comsol won't split the piston ring boundary surfaces (this alleviates the meshing problems of the rings). This should allow me to make a "swept mesh" on the piston rings thus reducing the degrees of freedom in the solid bodies while maintaining high quality solid mesh.A Swept Quad Mesh Within Free Tet - Quality Concerns. Posted 2017年3月18日 GMT+8 下午1:00 Heat Transfer & Phase Change, Geometry, Mesh, Structural Mechanics & Thermal Stresses Version 5.2 6 RepliesHi, I would like to build a "relatively" sophisticated swept mesh which would involve the step of building a nice 2D mesh and then sweeping that.

The COMSOL Multiphysics Reference Manual chapter on Infinite Elements, Perfectly Matched Layers, and Absorbing Layers.If the fluid body is bigger than the piston rings, Comsol won't split the piston ring boundary surfaces (this alleviates the meshing problems of the rings). This should allow me to make a "swept mesh" on the piston rings thus reducing the degrees of freedom in the solid bodies while maintaining high quality solid mesh.The model is in attachment. Two physics (bioheat physics and moving mesh physics) are included in model to simulate a laser ablation over a part of the bone. It worked well when there is only ...Meshing: The meshing methods of COMSOL Multiphysics includes free tetrahedral mesh, swept mesh, and boundary layer mesh. The picture shows the mesh of a flow simulation using higher-order elements. Meshing: The meshing methods of COMSOL Multiphysics includes free tetrahedral mesh, swept mesh, and boundary layer mesh.
