Installation of Julia Kite Power Tools

On Linux, it is suggested to first install the plotting Library Matplotlib, for example on Ubuntu with this command:

sudo apt install python3-matplotlib

This is not needed on Windows.

It is suggested that you create a folder for your kite simulators.

mkdir kitesims
cd kitesims
juliaup add 1.11
juliaup default 1.11
julia --startup-file=no -e "using Pkg; Pkg.add(\"TestEnv\")"
julia --project=.

You can copy-and-paste these commands into your terminal window. On windows, the key can be used, on Linux .

On the Julia prompt install the package:

using Pkg
pkg"add KiteSimulators"
pkg"add ControlPlots"
pkg"add Timers"

using KiteSimulators
init_project()
exit()

Tips

• Connect your laptop to a power socket before installing these packages.
• If you get an error and using Windows, you might have to download and install https://aka.ms/vs/17/release/vc_redist.x64.exe first and try again.
• If you still get errors, delete any old version with

rm -rf ~/.julia/packages
rm -rf ~/.julia/compiled/v1.11`
rm *.toml

and try again.

The commands above create the following directory structure:

It is suggested that you now create a Julia image that contains a compiled version of all the packages. Before doing that, close all other programs to make sure you have enough RAM (16GB RAM or 8GB + 8GB swap file is needed).

On the command line, enter for Linux:

cd bin
./create_sys_image

and for Windows, using the "Windows command prompt":

cd bin
create_sys_image

This will take 10 to 30 minutes but is only required once.

Running the KiteApp

You can now run the KiteApp with the command:

autopilot

from the bin folder. Alternatively, you can start it with a double-click on the file autopilot.bat in the bin folder.

On Linux, you need to type:

./autopilot

Execute the Julia REPL

To execute Julia on Linux with the commands:

cd ..
./bin/run_julia

and on Windows:

bin\run_julia

To quit the Julia REPL, type <CTRL><d> .
