![]() This technique allows for importing previously meshed structures, including legacy meshes, which can then can be used for any type of COMSOL Multiphysics simulation. For enabling a boundary condition on one side of the structure, COMSOL 4.3's new Mesh Selection operations can group elements into a new geometrical boundary. This nanotomography model of a lithium-ion battery microstructure was imported as a mesh. Thomas Royston and Ying Peng, Acoustics & Vibrations Laboratory, University of Illinois at Chicago. ![]() Generating a coarser mesh takes 10 seconds, when Virtual Geometry operations are applied to minimize the influence of non-essential geometry edges and surfaces. The meshing algorithm creates a default mesh in 30 seconds on a standard dual core workstation. This geometric representation of a lung was imported using the COMSOL CAD Import Module. This is fully coupled to the heat transfer simulation of the mold and polyurethane part, which was imported as a CAD geometry. The new COMSOL Pipe Flow Module allows for efficient simulation of the cooling channels using 1D pipe non-isothermal flow. The electrode material removal is represented by a moving mesh and can thus be considered as a process variable.Ĭooling of a steering wheel injection mold. Galvanic corrosion of a magnesium alloy (AE44) connected to mild steel in a salt-water solution. Visualized is the electrolyte potential on the surface of the structure. Before deploying the anodes, engineers would use the new COMSOL Multiphysics Corrosion Module to optimize the position of each anode for the best possible corrosion protection. This simulation is made possible by the large strain plasticity option available in the Nonlinear Structural Materials Module and the new, very powerful Double Dogleg solver.Īn oil rig structure immersed in seawater is protected by 52 sacrificial aluminum anodes. The bar experiences large-scale necking and plastic deformation across its central cross-sectional region. ![]() In this classic benchmark, a circular bar is subjected to a uniaxial tensile test, resulting in large deformations.
