Subject: FIDISOL/CADSOL Now Freely Available

The FIDISOL/CADSOL program package is now freely available for purely
scientific use.
FIDISOL/CADSOL is a program package for the solution of partial differential
equations. 2- and 3-dimensional systems of elliptic (stationary) and parabolic
(time-dependent) equations can be solved. The boundary conditions may be
arbitrary. The solution method is the finite difference method. For the FIDISOL
part the solution domain is restricted to be rectangular. For the CADSOL part
the domain is body-oriented, i. e. logically rectangular. There are versions
with an adaptive grid generation. For CADSOL dividing lines can be prescribed
allowing the solution of different partial differential equations in
different subdomains or allowing noncontinuous conditions inside the domain.

More information is available on the web site:
`http://www.rz.uni-karlsruhe.de/~fidisol/`.
The program and all kind of description can be downloaded directly from the
web.

Please notice: There will be no user support for FIDISOL/CADSOL as we do not
have enough manpower.
