COMSOL Multiphysics 4.4 is here!

Hello COMSOL Community,

The most powerful multiphysics software just got more powerful: We are excited to announce that the latest release of COMSOL Multiphysics, version 4.4, is now available for download. Learn about the new multiphysics coupling functionality, the enhanced user interface, and more at www.comsol.com/release/4.4

News in COMSOL Multiphysics
- New COMSOL Desktop interface for Windows with a ribbon design that provides easier navigation
- A completely new Multiphysics node in the model tree for setting up multiphysics models
* Combine physics interfaces to define your own multiphysics
* Choose from built-in multiphysics couplings
* View each physics interface as a separate node in the tree
- One-click select: hover-and-click selection method speeds up the modeling process
- Auto-complete search to quickly find variables to use in results in the Windows version
- Geometry subsequences for user-defined geometric primitives
- If/else statements in the model tree for conditional geometry creation
- Export mesh to NASTRAN file formats
- Time-unit handling in the solvers

News in add-on products
- Structural Mechanics Module: easy access to rotordynamic forces, updated shell-solid couplings, and fast method for contact
- Heat Transfer Module: fast methods for radiation in participating media, thermoelectric effect, and heating of biological tissue
- Acoustics Module: Linearized Euler equations for aeroacoustics simulations
- CFD Module: dramatically increased conservation of mass and energy for laminar flow
- AC/DC Module: now includes 167 nonlinear magnetic materials
- RF Module: ports on interior boundaries (reintroduced from version 3.5a)
- Particle Tracing Module: efficient method for particle-field and fluid-particle interactions
- Optimization Module: additional gradient-free method (BOBYQA) for dimensional optimization and additional gradient-based method (MMA) for topology optimization

New product
- Mixer Module: analysis of stirred mixers and reactors with tools for free surface modeling and non-Newtonian fluids

Why is it that Comsol prioritize on Windows users?

Re: COMSOL Multiphysics 4.4 is here!

Dear Felipe,

As you have pointed out, the ribbon is a great addition for Windows and I'd like to highlight that in the COMSOL Desktop environment, most of the functionality accessed from the ribbon is also accessible from contextual menus by right-clicking nodes in the model tree.

For those operations that are only available from the ribbon, such as selecting which desktop window to display, a set of menus and toolbars, which replace the ribbon for OS X and Linux, are available. The ribbon gives quick access to available commands and complements the model tree in the Model Builder window but there are also operations that are only available from the model tree, such as reordering and disabling nodes.

The user interface has been enhanced for all the operating systems that we support and more has yet to come...

Best regards,
Valerio

How to control equation system as v3.5 physics >equation system > boundary setting
?
Where is UMFPACK solver or the option instead it?

Hi Waleed,

To access the equations you have to display the Equation View subnode in the model tree: click the Show button and select Equation View from the Model Builder. Click the Equation view subnode and the corresponding settings window will show you detailed information about the implementation of each physics feature.

UMFPACK has been replaced by MUMPS, PARDISO, and SPOOLES.

Best,
Valerio

Re: COMSOL Multiphysics 4.4 is here!

Hi,
How to I clear stored solutions/meshing in comsol 4.4? There used to be edit option in earlier version but it seems like it is not there any more in 4.4.





Regards,
Johnson

Re: COMSOL Multiphysics 4.4 is here!

Hello Johnson,

If you are using Windows and COMSOL 4.4, please use these menu options:

Mesh > Clear Mesh
Study > Solver Configurations > Clear Solutions

Best regards,
Valerio
