Gensys-2401

Installation of "Mint213-gensys24" can be made in two ways:

1. As a Virtual Machine under VirtualBox
2. Via a deb-file

Updates in the new machine

1. Gensys-2401 is compiled with the new gcc-13 compiler, which gives better warning messages and improves execution times.
2. Some calculations has been changed to quad precision, to minimize the risk for truncation error.
3. New file manager program genfile-gtk, which behaves in a similar way to Windows Exporer does. Launch program genfile-gtk by clicking on icon to the left in the lower margin.
4. New terminal program genterm-gtk, which allows to resize the window without destroying the text in the window. Launch program genterm-gtk by clicking on icon to the left in the lower margin.
5. In script opdiff option "--ref" has been added. Option "--ref" will compare your input data file with a reference Master input data file.

Mplot

1. Check if directory "id" exists, minimizing the risk for launching program Mplot in a wrong directory.

Gen_calclib

1. New sub-command "func system_init" which picks up results from a UNIX-command. Example:
   Find the end of a track file Xtrac_stop, with the following command:
   func system_init Xtrac_stop= "tail -n 1 track_file.trax_wdesign | awk '{print $1+10.}'"
   Variable Xtrac_stop is required as input data to the commands func intpl_track_irr2 and func intpl_track_irr3. Command awk adds another 10[m] allowing for a trailing ramp after the track irregularities.
2. In file .mode, extend table #2 with three columns comprising of real part, imaginary part and complex absolute value in [rad/s].
3. Updated to version 23.2 of program CONTACT. Installation instruction for CONTACT, see below.
4. New input parameter check_nan for better debugging, when there is an error in the model.
5. Give warnings on all couplings that not are mounted in the center of the wheelset. It might be necessary to also include the axleboxes in the model.

Genfile

1. New menu item "Split pdf files" has been added. The new menu item can be found under Unix -> Postscript.
2. New menu item "Screenruler" has been added. The new menu item can be found under Unix.

Kpf

1. New input data command IPLOT_DIAGS which allows the user in detail to control the generated diagrams.

Installing of shared objects for CONTACT

In order to use CONTACT for calculating the wheel/rail-forces, do the following steps:

• Download file clibrary_contact_v23.2.tgz to your home directory $HOME.
• Uncompress the tar file tar -xvzkpf clibrary_contact_v23.2.tgz
• Go to directory ~/clibrary_contact_v23.2/bin
• Create a license file for CONTACT with the following command:

  LD_LIBRARY_PATH="linux64:."  ./caddon_license_linux64
  

  Give command: activate followed by your "License ID" and "Activation Password", which can be obtained by Edwin Vollebregt.
• To include CONTACT when calculating the wheel/rail-forces, launch tsim with the following command:

  LD_LIBRARY_PATH=~/clibrary_contact_v23.2/lib  tsim  runf/tang_ideal_contact.tsimf
