1. How to link files ".fwk3d" to Fachwerk3D:
   -------------------------------------
   
   Windows
   -------
   
   - Somewhere in Explorer you can set file types 
   - New:  fwk3d
   - Name: Fachwerk3D
   
   - Process "Open"
   - Application:
     C:\Windows\system32\CMD.EXE /c start /d C:\programs\fachwerk3d C:\Programme\fachwerk3d\fachwerk3d.bat "%1"
     
   - Other symbol - find - fachwerk3d/INFO/src/fachwerk.ico
     
     
   
   Linux
   -----
     
   a) rpm or deb used for installation
   
      File association done by the installer.

   
   b) Zip file fachwerk3d*.zip extracted to /home/USER/programs
      
      KDE:
   - Right click on a fwk3d-file, Properties
   - Click on small icon that shows a tool.
   - Description: "Fachwerk3D"
   - Click on icon - Other symbols
     "PATHtoFachwerk3D/fachwerk3d/INFO/src/fachwerk.png" - OK
   - Add: (using the path to the location where you have installed Fachwerk3D)
     konsole --workdir '/home/USER/programs/fachwerk3d/' -e '/home/USER/programs/fachwerk3d/fachwerk3d'


3. Insufficient memory for large models
   ------------------------------------

   If fachwerk3d interrupts the calculation throwing the message
   java.lang.OutOfMemoryError: Java heap space,
   more memory can be allocated:
   Edit the file fachwerk3d.bat/fachwerk3d and set the argument -Xmx:
   java -Xmx512m -jar fachwerk3d*.jar
