Version 5.3a, the latest release of this company’s Multiphysics software (photo), provides many enhanced simulation capabilities for users of computational fluid dynamics (CFD) analysis, including up to 40% improved performance for algebraic multigrid (AMG) and 20% for geometric multigrid (GMG) solvers, says the company. Chemical engineers will benefit from the built-in library for thermodynamics properties, which features models for gases, liquids and phase equilibria (gas-liquids). Furthermore, there is a new turbulence model available for a more accurate description of fluid-flow features. A predefined multiphysics coupling has been introduced for the modeling of heat and moisture transport in materials and moist air. The software also features the Cividis color table, which is optimized for people with color-vision deficiency (photo). Applications with very large plots or many graphics windows will see improved rendering performances, resulting in a more responsive user interface. — Comsol, Inc., Burlington, Mass.
