Versionsübersicht (deutsche Version)

Version 2.61 from April 3, 2001
Bugfix. Large circuit diagrams were not printed properly sometimes.

Version 2.60 from August 23, 2000
New Feature. The standard directory for FluidSIM circuits can be declared in the "festo.ini" file that is in the Windows directory: In the paragraph [FL_SIM_P_GB_M] (blue plug) or [FL_SIM_P_GB_W] (green plug) the absolute path is entered after the CT_DIR keyword.
The respective directories for the hydraulic versions are defined in the paragraphs [FL_SIM_H_GB_M] (blue plug) and [FL_SIM_H_GB_W] (green plug) respectively.

Version 2.59 from May 25, 2000
Bugfix. In very few cases the simulation freezes unexpectedly, and no inputs are accepted til the simulated circuit is reset or the simulation is stopped.

Version 2.58 from January 11, 2000
Internal. Contains several code optimizations.

Version 2.57 from October 4, 1999
Bugfix. Positioning of distance rules for rotated cylinders is more reliable.

Patch. The appearance of circuits that are pasted as metafiles
from the clipboard into other applications has been improved.

Version 2.56 from August 12, 1999
Bugfix. In rare cases, an internal assignment error of labels occurred during the simulation.

Version 2.55 from June 15, 1999
Bugfix. Angular, dashed lines could become rendered badly when printing circuits.

Version 2.54 from May 3, 1999
Internal. Adaptations for non-Latin character sets have been made.

Version 2.53 from March 30, 1999
Bugfix. Connecting two connections of the same T-junction led to a very special numerical problem.

Version 2.52 from March 19, 1999
New Feature. The printout quality of high resolution printers is improved by the fact that the line thickness is now computed independently of the printing device's resolution. Up to now the line thickness used to be too fine on high resolution printers, leading to unsatisfactory copying or faxing results.

Version 2.51 from March 5, 1999
New Feature. With a wrong configuration of the network printer, printing failed in FluidSIM (and in all other 16-bit programs). Note that this problem can be solved manually by the user. However, FluidSIM is able to detect the problem by itself and does correct printing despite a wrong network printer configuration.

Version 2.50 from February 2, 1999
Bugfix. When starting FluidSIM by means of a file name extension, the program libraries were not found in particular situations.

New Feature. A file "user.txt" can be created, which user-specifically disables features for trouble shooting. If this file contains a line "3 <film path>", the educational films are loaded from this place. <film path> must designate the complete DOS path, follow the "8+3" letter syntax convention, and must not contain spaces.

Bugfix. In FluidSIM-P, the cylinder names were not always saved.

Bugfix. Some font attributes of the text components were not saved.

Version 2.49 from November 5, 1998
Bugfix. Having opened a color bitmap, a color palette adaptation was not always performed.

Bugfix. If more than 100 user interactions were pending, FluidSIM crashed.

Bugfix. A "Division by zero error" occurred on fast PCs (> PII 333 MHz).

Version 2.48 from March 23, 1998
Bugfix. The circuit preview produced display faults in rare cases.

Bugfix. Sometimes, the circuit preview showed not all circuit directories.

Bugfix. The line type of pneumatic lines was not saved.

New Feature. The playback of educational films in *.mpg format is possible now.

New Feature. Simulations that contain a lot of switching operations run faster now.

Version 2.47 from March 5, 1998
New Feature. Generates a clear message if the number of licenses allowed by the WIBU network connector is reached. Note that only the version 2.47w (observe the "w") is WIBU compliant. Versions without a "w" continue in accepting only the MARX connector.

Bugfix. Although non-existing, a short circuit in the electric circuit part was messaged in rare cases.

Version 2.46 from December 18, 1997
New Feature. FluidSIM adapted respecting the WIBU network connector. Note that only the version 2.46w (observe the "w") is WIBU compliant. Versions without a "w" continue in accepting only the MARX connector.

Version 2.45 from October 30, 1997
Bugfix. Some time-controlled components caused a crash in particular situations.

Bugfix. Stopping simulation during state computation caused a crash in particular situations.

Version 2.44 from October 23, 1997
Bugfix. Mouse drivers with enabled lefty characteristics caused problems.

Version 2.43 from October 6, 1997
Bugfix. The scrolling step width was adjusted too large in some situations.

Version 2.42 from September 10, 1997
Internal. Some code optimizations respecting the display of state values have been made.

Version 2.41 from July 10, 1997
Internal. Some code optimizations respecting DXF export, the saving of clipboard files, and the saving of undo files have been made.

Version 2.4 from May 28, 1997
New Feature. Fluidic lines can now be labeled as main lines and control lines respectively. The latter are shown dashed.

New Feature. The electric counter now comes with two additional connections, which enable its resetting to zero.

Internal. The physical model of the AND-valve (two-pressure-valve) has been reworked.

Version 2.3 from May 22, 1997
Bugfix. When connecting T-junctions FluidSIM crashed in rare cases.

Bugfix. Having loaded large circuits with a small number of lines FluidSIM crashed in rare cases.

New Feature. FluidSIM now runs under Windows NT.

Version 2.2 from April 3, 1997
New Feature. FluidSIM now can be installed on a network file server.

Bugfix. Under Windows 95, FluidSIM files were not always removed during De-installation.

Bugfix. Opening a presentation could fail if a presentation with the same topic was already opened.

New Feature. Opening large presentation now runs considerably faster.

New Feature. When saving settings, also the last opened topic of a presentation is memorized.

New Feature. The educational films on the CD are rendered at a better quality.

New Feature. Also stalled pressures are computed during simulation (concerns FluidSIM-H only).

Version 2.1 from March 2, 1997
Bugfix. The component library was sometimes not saved.

New Feature. The file menu now shows the 8 recently opened files.

Version 2.07 from January 20, 1997
Internal. Management of the animations improved.

Bugfix. The selection of the local and global settings of the states display behaved inconsistently.

New Feature. When changing the slow motion factor during simulation, the elapsed simulation time is recomputed correctly.

Bugfix. The local display settings of a few components were not saved.

New Feature. When reasonably connected, the two-pressure-valve can be flown through in opposite direction now.

New Feature. If one tries to start both the full and the educational version of FluidSIM indeterministic situations are intercepted. (As a matter of concept, two FluidSIM applications cannot run at the same time.)

Version 2.06 from November 4, 1996
Bugfix. The presentation dialog box could crash in some rare cases.

Version 2.05 from October 15, 1996
Internal. Some modifications respecting the error handling were made.

Version 2.04 from October 10, 1996
Internal. An exceeding of the internal working capacity is detected more reliably.

Internal. Some code optimizations have been made.

Bugfix. When loading a circuit from a drive other than the installation drive, program modules were not always found.

Version 2.02 from September 10, 1996
Bugfix. Pressing the "STOP"-key during state computations sometimes caused problems.

Version 2.01 from June 26, 1996
First release of sales version 2.

Known Problems
Up to now, all available Windows 3.1 graphic drivers "Spea Bigwin" can lead to system crashes because of a buggy implementation of some Windows-API commands, which handle off-screen bitmaps.

Some graphic drivers are not capable of correctly rendering the component animations because they provide no support for RLE4-compressed bitmaps.

The Postscript printer driver of Windows 95 crashes, if a window containing circuit previews shall be printed. Presumably some bitmap API functions are flawy implemented .

Angular lines are not printed with particular combinations of some graphics and printer drivers.

Some components are not drawn with some particular graphics drivers.
