Installation

Step 1 – Basic Set Up

Unzipping Wildkatze.Release.2023.6.30.x86_64.7z we get:

install 01

Make directory called dravvya in home ($HOME) directory.
Copy the contents of Wildkatze.Release.2023.5.30.x86_64.7z in $HOME/dravvya folder.
Copy the license file license.wildkatze.dat in the $HOME/dravvya/license folder. This license file shall be provided by Digital Solution Inc. The license file provided with basic setup will not be identified by the solver.
At this point $HOME/dravvya folder has all relevant files along with a valid license.

Step 2 – Installing Openmpi

Wildkatze uses Openmpi, a typical setup shall go as follows:

sudo apt-get install libibnetdisc-dev
wget http://www.open-mpi.org/software/ompi/v1.10/downloads/openmpi-1.10.3.tar.gz
tar -xvzf openmpi-1.10.3.tar.gz
cd openmpi-1.10.3
./configure --prefix=$HOME/dravvya/openmpi110
make && sudo make install

Step 3 – VTK for Client GUI

Setting up VTK is no longer necessary because VTK Panels in GUI are no longer loaded.

We copied solver into $HOME/dravvya/

install 02

However this would mostly likely fail to launch the GUI for failing to load vtk related classes. To properly start GUI one need to set environment variable LD_LIBRARY_PATH to $HOME/dravvya/vtk

install 03

One can now launch Client GUI using

install 04

Java

In case the GUI fails to load for absence of Java, one can install Java with following:

sudo apt-get install default-jdk
sudo apt-get install default-jre
sudo apt install openjdk-8-jdk

Step 4 – Solver Launch Scripts

We copied solver into $HOME/dravvya/

install 05

There is a set of .sh or shell script files present in bin folder. After copying files to $HOME/dravvya they shall be present in $HOME/dravvya . These files are used to run the solver in various modes.

Creating solver.sh file for launchig wildkatze solver

Please edit the .sh files present in bin folder (int installation) with proper $HOME values.

Example solver.sh to launch wildkatze with 4 processes

 /home/savya/dravvya/openmpi110/bin/mpirun -np 4 /home/savya/dravvya/bin/wildkatze -l  /home/savya/dravvya/license/license.wildkatze.dat "$@"

We now set up the GUI script.

GUI script wildkatzeGUI.sh

One shall replace the $HOME variable in wildkatzeGUI.sh. This script is used to launch the GUI.

Step 5 – Running the Solver

Solver in Console Mode

Once the solver.sh script is set up, starting solver in console mode is:

source solver.sh

This launches the solver in console mode:

install 05

Solver in Client Server Mode (with GUI)

To start the server at port 5010 we use

solver.sh -s 5010

install 07

One can notice 5010 in above picture. This is the port on which server is listening for incoming connections from GUI.
Now user shall start GUI and connect the server on this port.

Client Mode

To start GUI or client

solverGui.sh

This runs GUI as

install 08

install 09
