There was a great deal of positive feedback from users
following the release of FIDAP 8.7 in December 2002.
The ability to run volume of fluid (VOF) simulations
in parallel was reported to be especially welcome.
Simplification of the setup of the free surface and evaporation
models, the new partially coupled solver, and
the bundling with FIELDVIEW, FIDAP's new postprocessor,
are the features that generated the most enthusiasm.

Some users reported that the time between releases
is sometimes too long, especially when they are waiting
for the fix of a defect critical to them. To respond
to this request, releases will become available on the
Users Services Center more regularly. The first of these
is FIDAP 8.7.2, which is now available for download from
the USC. This maintenance release addresses many issues
that users have recently reported, with a special focus
on applications involving VOF and simulations being run
in parallel. For example, in FIDAP 8.7.2 VOF demonstrates
robust performance when run in parallel on more
than 2 CPUs. Inconveniences that occurred with userdefined
subroutines in parallel VOF simulations have disappeared.
The accuracy of the results (as indicated by
mass balances) when tet meshes are used has been
improved. The performance of other models run in parallel
has also been carefully addressed. Some former difficulties
such as parallel runs on Windows 2000 with SLIP
entities, simulations involving FSI, or the use of the FDSTOP
file, have vanished in the new version.
