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

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梞eshing, assembly, and solving梟ow 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 simulationSpice 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抯 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.
