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

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


2. File dialogue "Save" or "Load" hangs. (Windows only):
   -------------------------------------------------------

   Happens in certain circumstances when a fachwerk file is loaded using the command line.

   Alternatives
   1) Solve problem
     Possible cause: Links on the desktop pointing to non existing files.
   2) Work around
     First "load background". Afterwards "save" works.
   3) Work around (2)
     Start fachwerk with option --safe_mode.


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

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