Hey guys, I am new to kangaroo and just wondering if I am doing anything wrong. A “simple” definition takes a long time to process ? Also is there any way to have a time constraint for calculation and not just on/off? Sometimes it is impossible to disable the process and I have to force quiet Rhi…

So it is iterating quickly, just the movements at each step are small. The size of the steps is affected by the ratio of the strengths of the goals. In this file the strength of the OnMesh goal is extremely high relative to the gravity on the particles. If you increase the value in the Z componen…

Thank you Daniel. It works. The delay of the on/off switch I would assume is a limitation of Grasshopper and my system ? What would be a good solution to limit the simulation to a specific timeframe?

Here’s the speed I get on my desktop with 3k particles: (this is on an i7 4790k, so decent but not crazy powerful) Another option to control how the simulation runs is to use one of the other solver components such as the StepSolver, with a slider connected, then it only updates when…

Wow :open_mouth: It is soooo slow on my Mac, I can’t orbit my viewport at all ((( I will try a step solver tomorrow

Unfortunately it is still very slow. I think it is Grasshopper/Mac problem ?! It looks like Kangaroo works fine, but Rhino Viewport and Grasshopper space not active while simulation is running. I am testing it on Mac Book pro 2017 2.9 GHz Intel Core i7

Thanks, I’ll look into this and do some more testing on the speed of the Mac version.

Thank you Daniel I will try same file on different Mac tomorrow as well …

Hi Daniel, I tried the definition with different mesh and on a different iMac 2012, 3.4 GHz Intel Core i7. Simulation works fine if I reduce the OnMesh strength parameter, but Rhino viewport and Grasshopper are not responsive while simulation is running. I also have a technical question regarding…

I experience the same problem. Even very simple simulation in kangaroo works very slow, e.g. Basic wind on mesh simulation takes 30.9 second with zombi solver.

Can you share the file, so I can confirm the problem here is specific to the Mac version, rather than something else in the setup

There you are. It is very simple wind simulation. It works, but very slowly 26.6 sec. Wind_test.gh (12.1 KB) [30]

Anyone who can help are welcome. @DanielPiker @dan @diff-arch
Kangaroo for Mac always had a problem, wondering why nobody reported.

Thank you guys
