FrageHaving started the simulation, one of the following error messages appears:  
  • "Invalid system call or division by zero detected.
  • "Win386: A program error has been detected..." 
AntwortThis problem may show up on fast PCs, such as Pentium II 300 MHz and higher. Please install the newest update.
FrageHow to configure a network installation of FluidSIM where several users  
  • use the same FluidSIM installation,
  • need no write permission for the central FluidSIM directory,
  • have individual options/configuration files in their respective home dictionaries?
AntwortFirstly, install FluidSIM on the server in a shared directory. Secondly, for each user, set up a directory (e.g. G:\HOME\USER1\FL_SIM_P) and copy the directories aq and misc (from the shared directory). Thirdly, for each user, create an association from fl_sim_p.exe that refers to the user's working directory. 
Example:

FrageCircuit printouts on a high resolution printer (600 dpi and more) appear unsatisfactory, because of the very thin lines. 

AntwortInstall the newest update , which has a print routine that works independently from the printer's resolution.

FragePrinting on a network printer does not work. However, network printing with other programs works. 

AntwortSometimes it is necessary to assign a printer port to the network printer. This can be accomplished as follows. Open the printer's properties dialog box in the Windows control panel. Add a new port (e.g. LPT1 or LPT2 if a local printer is already connected) and select this port as printer output.

FragePlaying the educational films does not work in the network. 

AntwortTwo possibilities exist to play the educational films without having a local CD-ROM drive. 
1. Use the CD-ROM drive from some other PC in the network 
Necessary pre-condition: The respective PC has both global access enabled and a drive letter assigned for the CD-ROM. 
2. Use a hard disk drive in the network 
Necessary pre-condition: The newest update is installed. Moreover, create a file user.txt in the misc directory of the FluidSIM installation. Edit this file and insert the text "3 <path>", where  <path> is to be replaced by the absolute path pointing to the avi-files (observe the blank following the number). 
Example: 
Text File  
The educational films can be copied from the FluidSIM CD. They are located in the directory fl_sim_p\mov (and  fl_sim_h\mov respectively)
