Users can now simply record a set of operations, like a macro, and use the resulting method while setting up or solving a model. With the introduction of model methods in version 5.3, COMSOL says that it is easy to automate repetitive operations directly in the Model Builder.

This COMSOL 5.3 image depicts a vibration and noise analysis of a 5-speed synchromesh gearbox inside a vehicle with a manual transmission. A new option for automatic geometry defeaturing through virtual geometry operations is now also available. Users working with models and geometry requiring the use of several element types should benefit from the automatic generation of pyramidal elements to handle the transition between swept, hexahedral, prismatic and tetrahedral meshes, says COMSOL.

Further, turbulent flow modeling is said to now offer more robust computations with automatic treatment of walls, a feature that blends high-fidelity, low-Reynolds formulation with wall functions.īeginning with version 5.3 the Model Builder now more rapidly deals with geometry and mesh operations for models with large arrays and complicated solid operations in 3D.

COMSOL says that the simulation process is more robust for problems such as fluid-structure interaction as shown in the solar panel simulation here.

Users can quickly set up simulations that combine wires, beams, surfaces and solids in the same model, says COMSOL, adding that users can combine BEM and finite element (FE) methods in multiphysics simulations.ĬOMSOL 5.3 introduces a new Algebraic Multigrid (AMG) solver for CFD (computational fluid dynamics) analyses, which allows for solving large fluid flow problems with a single mesh level. Additionally, geometry and mesh performance improvements from automatic pyramid element transitions and automatic removal of geometric details are reported.ĬOMSOL explains that for modeling electrostatics and corrosion effects, version 5.3's new BEM capabilities will enable users to simulate models with infinite domains and voids. CAD import is now up to 5x faster, while loading and saving MPH (COMSOL Multiphysics) formatted files see a 2x to 10x performance boost. By way of example, COMSOL reports potential speedups for such operations as selections of domains, boundaries, edges and points, as well as OpenGL rendering range up to 10x. Image courtesy of COMSOL Inc.Ĭompared with a very recent edition, existing users could see COMSOL version 5.3 handle large models anywhere from 2x to 10x faster depending on the details of the model, according to the company. COMSOL 5.3's new Boundary Element Method (BEM) functionality was used to create this simulation. A Donnan potential shift over the interface is calculated automatically from the concentrations of the charge-carrying ion on each side of the interface.This image shows a numerical simulation of the electrochemical potential distribution along an oil rig in sea water.

This condition is typically used in electrochemical cells containing both free electrolytes and ion-exchange membranes, for instance, in dialysis problems. The new Ion-Exchange Membrane boundary node specifies a boundary condition where the flux of ions is continuous, but where the electrolyte potential is discontinuous and is described by a Donnan equilibrium. A zone electrophoresis problem is set up for separation of a sample containing aniline and pyridine.Īpplication Library path for the Zone Electrophoresis tutorial: Chemical_Reaction_Engineering_Module/Electrokinetic_Effects/zone_electrophoresis Ion-Exchange Membrane Internal Boundary Condition in the Tertiary Current Distribution, Nernst-Planck Interface This tutorial serves as an introduction to the Electrophoretic Transport interface.
