COMSOL brings a major upgrade to its customers that includes multicore support, new solvers, and many enhancements to the add-on modules. To see a complete list of new features and models, click here
Multicore processing reduces time to solution
Flow around a set of pillars in a SAW sensor
COMSOL Multiphysics 3.4 delivers the utmost in computational speed by leveraging multicore processors and shared-memory parallelism. Each step of the simulation workflow—meshing, assembly, and solving—now executes in parallel. COMSOL Multiphysics 3.4 uses the maximum number of cores available on the system, and users have complete control over the number of processors dedicated to their simulations.
New segregated solver and stabilization techniques raise limit on model size
Heat transfer from an impinging jet
A segregated solver with an easy-to-use interface reduces memory consumption significantly when solving large problems, such as fluid-structure interaction (FSI) or wave propagation in thermally deformed structures.
A major upgrade to COMSOL's iterative solvers pushes performance for fluid dynamics to new heights. New state-of-the-art Galerkin least squares (GLS) stabilization techniques complement the iterative solvers, enabling large fluid flow problems with millions of degrees of freedom to be solved.
Multiphase flow and free convection
Emulsifier droplet production
The Chemical Engineering Module has been improved with a powerful modeling interface for the simulation of multiphase flow. With it, users can now simulate bubbly flows, such as in scrubbers, and also set up mixture models for simulating emulsification, sedimentation, and other separation processes.
Users can now expand their simulations to include variable-density flow and free convection. Engineers will find these new capabilities particularly useful when solving coupled-flow and conjugate heat-transfer problems commonly encountered in electronic cooling and heat-exchanger analyses.
Parameter estimation
Upgrades to the COMSOL Reaction Engineering Lab include a powerful new interface for running nonlinear parameter estimations on multiple sets of experimental data. Outputs now display with confidence intervals and standard deviations.
FEA models as part of a circuit simulation
Spice import
Version 3.4 makes it easy to build and run COMSOL models as part of SPICE-based circuit simulations thanks to the AC/DC Module’s new SPICE user interface. Another exciting new feature for electronics, electrical components, geophysics, and electrochemistry applications is small-signal analysis for AC impedance studies.
Fatigue analysis
The Structural Mechanics Module now lets users predict high- and low-cycle fatigue damage. A suite of COMSOL Script functions calculate fatigue damage from inputs made up of loading data and deterministic, stochastic, or even nonproportional material fatigue data.
