There is a lot of improved functionality in GEM-Selektor v.3.3 or higher
compared with v.3.2. For backward compatibility, all modelling projects
created in GEM-Selektor v.3.2.x or earlier, will open and work normally
in GEM-Selektor v.3.3.x; accordingly, GEMS3K I/O files exported from
GEM-Selektor v.3.2.x are readable and will work in coupled codes and
examples using GEMS3K v.3.3.x.
Immediate extension of old modeling projects
in GEM-Selektor v.3.3.x with newly created Phase records, remaking
existing Phase records, or via Project remake/extension wizard is
possible. Before doing that, the user needs only once to open the
project; switch to Database Mode; open the Phase window; and remake
one-by-one all Phase records available in the project (saving each
record back after remake).
Note that if some Phase records remain in the
"old" format (i.e. not remade) then this will lead to errors or crashes
during calculations of equilibria in systems from this project. So, it
is essential that ALL Phase records go once through the Phase remake
wizard! Even opening and closing a modeling project once in the
GEM-Selektor v.3.3.x will render this project unusable in earlier
versions of GEM-Selektor (3.2.x or less).
For these reasons, if you have used
GEM-Selektor v.3.2.x or earlier, we recommend not to upgrade it, but to
install GEM-Selektor v.3.3.x to a new location in your PC, check it, and
then copy your old modelling projects into the work project directory of
the new version (usually like \MyGEMS33\Library\Gems3\projects).
Previously released GEM-Selektor v.3.4.2
packages can be downloaded using the links below.
If, in Windows or Linux, you have a previously installed GEM-Selektor
package older than rev. 2370.830, then we recommend installing the current
package to a different location and copy your modeling projects over.
There are two reasons: (i) some files in /Resources/DB.default have been
renamed in preparation of an updated PSI-Nagra thermodynamic database;
(ii) the Project record format has been extended, so a newly created or
expanded project will not be readable by earlier revisions of
GEM-Selektor. In Mac OS X, first back up your project directory
(/users/<home>/Library/Gems3/projects); then move Gems3.app from
/Applications to trash, and put a new one from dmg to /Applications.
