Major News in COMSOL Multiphysics® Version 5.6

COMSOL Multiphysics® version 5.6 features faster and more memory-lean solvers for multicore and cluster computations, more efficient CAD assembly handling, application layout templates, and a range of new graphics features including clip planes, realistic material rendering, and partial transparency. Four new products expand the modeling power of the COMSOL Multiphysics® software. The Fuel Cell & Electrolyzer Module provides engineers with state-of-the-art modeling and simulation tools for fuel cells and electrolyzers. The Polymer Flow Module can be used to design and optimize processes involving non-Newtonian fluids including multiphysics effects. Control systems engineers can use the new LiveLink™ for Simulink® product for cosimulation of COMSOL Multiphysics® and Simulink®. The Liquid & Gas Properties Module is used for computing properties for gases, liquids, and mixtures.
