A new boundary element method formulation enables analyses of acoustics models that are up to an order of magnitude larger than previous versions. Certain classes of viscoelastic structural analysis are now more than 10 times faster. With all of these improvements, the CPU time improvements can even exceed 50% for time-dependent CFD,” said Jacob Ystrom, technology manager of numerical analysis at COMSOL. For CFD, we have improved the coupled velocity-pressure preconditioner and also added a brand new preconditioner that decouples the updates of these variables. The improvements are even more pronounced when using clusters, giving improvements in the range of 20–50% for both CPU time and memory requirements. These improvements benefit most models using these solvers, giving performance improvements up to 30%. "In version 5.6, we have made general improvements to both the algebraic multigrid and the domain decomposition solver technologies. Solver performance has greatly improved in version 5.6, to the benefit of COMSOL® users working with large models that have millions of degrees of freedom. Four new products expand the capabilities of COMSOL Multiphysics for modelling fuel cells and electrolysers, polymer flow, control systems and high-accuracy fluid models.įaster and More Memory-Efficient Solvers for a Wide Range of Applications A range of new graphics features - including clip planes, realistic material rendering and partial transparency - offer enhanced visualisation for simulation results. The new COMSOL® version 5.6 features faster and more memory-lean solvers for multicore and cluster computations, more efficient CAD assembly handling and application layout templates.
