KiteViewer 0.5.1 released, now with one point model

[Uwe Fechner]

Dear all,

The first version of KiteViewer is released, that includes also a simulator based on the one point kite model (particle
system with segmented tether).

https://github.com/ufechner7/KiteViewer/releases/tag/v0.5.1

It should work on Linux, Windows and Mac.

Feedback regarding Mac wanted, because I don't have one where I could test it.

To start the simulation, click the button "START". To steer the kite, use the right and left cursor keys.
This simulation is not yet very useful, because manual steering is very difficult, and an autopilot not yet included.
But it already shows the potential of Julia: The simulator is about 20 times as fast as the original Python/ Numba based
code and is able to simulate systems with a lot more tether segments in real-time.

I intend to work weekly on this project next year in the context of WP2 “Reference models, tools and metrics” of IEA
Wind Task 48, hopefully supported by my current employer, ABB.

I got already positive feedback from Uni Stuttgart in Germany where they started to use my project.

Enjoy Christmas, and happy simulating!

Uwe

This is great, thank you! And Julia has been a good language to learn.

Sorry for prodding, but any thoughts on when you think you'll have the 4-point model integrated? I'm debating waiting, attempting the integration myself or just spinning up an old Ubuntu VM and using the original Python version. Currently bumping into the issue where steering the 1p model produces jumps in the kite orientation.

Any thoughts on if going back to the old Python version and Ubuntu 12.04 is a good idea? It doesn't seem like there are any negative effects on accuracy/usefulness, just runtime, but I could be mistaken.

Thanks in advance!

I will try to add the 4 point model to KiteViewer (well, actually to KiteModels.jl) next week....

And going back to Ubuntu 12.04 is not really a good idea, because it is not secure to use an operating system that is end-of-life (without any security updates)...

Just keep an eye on https://github.com/ufechner7/KiteModels.jl :)
