WELCOMES TO Z88 !
Z88 for UNIX and Windows
is Freeware and is protected by the GNU General Public License, see next pages.
Z88 is compact and fast
and was developed for PCs initially. Today, Z88 runs properly on PCs with LINUX
and Windows starting with Windows95 to XP and powerfull UNIX workstations and
servers, however. Simple to compile and to install. Handling is simple. Z88
comes with context sensitive online-help and a user- friendly command
processor. Successfully proved by countless Windows-, UNIX- and LINUX installations
worldwide. For static calculations in mechanical engineering and building &
construction industries. Absolutely transparent for the user as input and
output are handled by text files.
Z88 has deliberately
been designed as a compact and fast system. Thus, its use is restricted to
static calculations. Z88 does not want to compete with professional FEA
programs for workstation or mainframes which can do really everything, but are
hardly payable and complicated to operate. While you are still puzzling about
installation and start of some programs of this genre also in the PC class, you
have already calculated the first examples with Z88. And the online-help is
always only one keystroke or mouse click away. The Z88 system may operate with
English or German language depending on your setting (ENGLISH or GERMAN) in the
file Z88.DYN.
The new version 12 looks
very similar to version 11 but now complete 64 bit support is supplied for UNIX
and LINUX. In addition – and this required a large revision of the solver
programs – surface and pressure loads are supplied which is very interesting
for importing NASTRAN files from Pro/ENGINEER.
If you already have FEA
experiences, you can start at once. If you are a beginner in this area, i would
recommend secondary literature. Here are a few choices:
·
Zienkiewicz, O.C.; Taylor, R.L.: The Finite
Element Method, Volumes 1-3, 5th edition, Butterworth- Heinemann
and John Wiley & Sons, 2000
·
Bathe,K.J.: Finite Elemente Procedures.
Prentice Hall, 1995
· Schwarz, H.R.: Methode der finiten Elemente. Teubner publishing house,
3rd edition, Stuttgart 1991 (in German language)
· Rieg,F.; Hackenschmidt, R.: Finite Elemente
Analyse für Ingenieure. Hanser- Verlag, München Wien 2003, 2nd
edition (in German language)
If you’ll improve Z88 please
give me your feedback. If you want to compile Z88 for UNIX any C compiler along
with a Motif and a OpenGL
library should work fine - i've tested the GNU gcc and the C compilers from SGI and SUN. If you want to compile
Z88 for Windows any kind of C or C++ compiler should work fine - i've tested
the free LCC and the C/C++ compilers
from Microsoft, Borland and Watcom.
And because Z88 is bound
to the GNU General Public License you are to present your improvements and
modifications to the public including the source code - that's a point of
honor. Promote the idea of the free software according to GNU-GPL! Please see
