COMSOL Version 4.2

Dear Colleagues,

We are delighted to announce the release of COMSOL Version 4.2!
This is a major upgrade which expands multiphysics applications for
mechanical, fluid, electromagnetics, and chemical simulations as well
as for CAD interoperability.

Most notable in this release are the many new and useful capabilities
for geometry and meshing, solvers, postprocessing, as well as with the
user interface. Version 4.2 also expands the applications covered by
COMSOL with three new application modules - Microfluidics, Geomechanics,
and Electrodeposition - and new LiveLink interfaces for AutoCAD® and
SpaceClaim®.

For an extensive list of the exciting new features, visit
www.comsol.com/4.2.

Feel free to contact your COMSOL representative to learn more.

Best regards,
Jeff Hiller

Dear All

Yes indeed, in the new release there are nice complements, among other in the postprocessing, to allow us end user to gain time, and many "small" very useful enhancements all over.

The only thing: I'm getting lost in the multiplicity and splitting of the toolboxes/physics, as I'm using and mixing many, it's getting less obvious to understand which modules are required, probably that is the cost of true "multi-physics"

By the way for us in Europe this link works better:

Hi Ivar, I guess this problem gets more prominent the more modules you have licensed. Here is the key: Right click a feature in the model tree and select Properties. Example: If you have "Laminar Two-Phase flow, Level Set (tpf)", right-click that and select Properties. Under the Used Products section you will see "COMSOL multiphysics" and "CFD Module".

You can do this also on boundary conditions and other features that require a certain product. If a feature is available in more that one add-on module and you are licensed to all of them, the first product key available will be shown in the properties section.

If you want to check the entire model file, click the root node in the model tree.

For a full specification of features and products, please refer the the Specification Chart on the web:
www.comsol.com/products/specifications/

kind regards
Niklas

Hi Niklas

Indeed you have added several nice new features to help us understand "overriding", physics "usage" etc in v4.2.
I need some time to discover them all :)

But my remark went also in view of us justifying w.r.t our management the ROI of COMSOL and the different modules, for each module, and why (it's an exercise I must prepare each year). This is no criticism, but you are now covering in detail so many physics that one easily become lost. And your specification list is detailed and impressive, indeed

After you install version 4.2, you should download and install the first update for version 4.2.

Hi !
Just installed 4.2 and wondered: does update 2 cover the issues in update 1?
I have installed update 2, should I install update 1 as well ?

Thanks

In order to make comsol (linux version) executable for users other than root the update to 4.2a (134) needs in addition to

chcon -t textrel_shlib_t [installdir]/comsol42a/lib/[platform]/lib*

the command

chmod 755 [installdir]/comsol42a/lib/

Regards,
Dominik

The update program for 4.2a update 1 (comsol_4.2.1.134_win.exe) suggests to extract the updated files to:
C:/Program Files/COMSOL/COMSOL42a
even though I have installed comsol in
C:\COMSOL42a
It is easy to make a mistake here.

Hi

you are right, but on the other hands it's always best to install a programme at its default location, also because Win OS expects the programmes to be in their default directory, where file access rules of given settings are applied by default

I believe it rather easy for you to redirect it, but as for FEM one should not forget to verify what one is doing, at each step ;)

Good luck
