Comsol has introduced Comsol Multiphysics 3.5, an upgrade of its engineering and scientific software environment for modelling and simulating any physics-based system. 

Expanding and facilitating Comsol's interoperability with third-party CAD/CAM/CAE applications, version 3.5 provides new Parasolid file format support and a new bidirectional Autodesk Inventor interface. New solvers, coding, and usability enhancements, as well as a wealth of new functionalities, application modes, and material models and properties in Comsol's suite of discipline-specific modules boost efficiency and productivity to new levels.

Raised efficiency, increased performance, and reduced memory requirements throughout Comsol Multiphysics 3.5 is achieved by the implementation of new solvers and revised implementation of the existing ones. Benchmark tests show that version 3.5 is more than three times faster for large flow models when compared to version 3.4.

Solving is substantially faster for time-dependent structural mechanics, electromagnetic, acoustics, and fluid-flow simulations using a new solver. You can also cut memory usage by as much as 50 per cent for common dynamic multiphysics simulations, such as Joule heating, with the new time-dependent segregated solver. This solver also offers new flexible settings that make setting up problems with various multiphysics couplings easier and faster.

Two to eight times faster time-domain wave simulations and fluid flow simulations are now achieved through solver enhancements. Larger problems can be run using the new out-of-core solver, which utilises disk memory for efficiently storing intermediate results on 32-bit and 64-bit computers. Optimised code has boosted shared-memory parallelism speedup by 20 per cent.
