So, if having an accurate solution to your problem is of some importance, you will need to study it carefully, and to not trust either model too much, until you better understand what is going on. It could be that you made poor choices in meshing, solver settings, boundary conditions, constraints, etc. but only a little bit more! And if there are big differences in results, then your problem set-up is probably a rather poor one, in either one or both versions of the code. Without any additional info, I would trust the newer version a bit more. Your particular set-up may be more valid (i.e., a better approximation) in one version than the other. But probably more important is how you (not Comsol) actually set up the problem. Version 5.3 and 4.3b differ in some ways that (obviously) can impact the nature and accuracy of those approximations. That said, all finite element models are only approximations to reality. You should, of course, check to see that in your new version, you have represented the problem in the same way (and that it was not mangled during input or conversion). The folder is only accessible with a DESY username and password.There are a large number of possible reasons. All information needed can be found under COMSOL Downloads & Licenses (or in /afs/sy/products/source/comsol/).
NIST COMSOL 5.3 MAC OSX
The installation procedure is very similar for Linux, Mac OSX and Windows.
NIST COMSOL 5.3 MANUALS
Some of the manuals can also be found in the COMSOL installation folder, on maxwell have a look at /software/comsol/5.2/multiphysics/doc/pdf/. COMSOL comes with an extensive Help-System. Asking for support at COMSOL you will need the license number (check "Licensed products" under "Options"). Getting supportįor basic support contact in-depth technical questions the COMSOL technical support is available. It is hence advisable to redirect COMSOL temporary data. Note: COMSOL stores large amount of files and data in /tmp and the home-directory. In general, accessing maxwell via FastX2 will be give a considerably better experience than using ssh for remote access. # Alternatively the setup can be initialized via ~]$ module load ~]$ module load ~]$ comsolĬheck for information about rendering. Usually Comsol Multiphysics can be invoked directly as a (versioned) ~]$ /software/comsol/5.2/multiphysics/bin/comsol # or if using remotely, you might need to specify the ~]$ /software/comsol/5.2/multiphysics/bin/comsol -3drend sw Using COMSOL Multiphysics (MAXWELL only!) Likewise access to installation media is only possible with a DESY-account (web) or from within the DESY-intranet (afs). Please note: access to the license server is not possible from outside DESY. Any other usage, in particular for industrial application, services for industrial partners or in co-operation with industrial partners is prohibited.
