Works OK, but is very slow on my PC (running about 2% of simulation speed). You could use a scissor mechanism for a muscle string. Since there are (9) muscle strings with (40) powered axles each, and since you only need (1) powered axle to power a scissor mechanism, you could reduce the powered axle count from 360 to 9 if you choose to use scissor mechanisms.

Yes you are right.
Thanks for your advice.
The scene is slow.
I chose this type of mechanism because when it contracts, the muscle swells and gives a "realistic" effect.
In your opinion, if I use a scissor mechanism, does the swelling effect of the muscle remain or contract linearly?

A scissor mechanism should give the same effect as your present muscle fibers. Your present muscle fibers look something like this -<>-<>-<>-<>-<>-<>-. A scissor mechanism muscle fiber would look like this -<><><><><><><><><>-.

OK thanks!
I try.
I'm curious to see the difference between the two mechanisms!

Hi s_noonan.
I tried to create the muscle with the scissor mechanism but I didn't like the result.
I spent two hours trying.
Movement becomes unnatural.
I prefer my slow scene.
Thanks, you always give me a lot of stimuli!

Thanks for trying. Maybe I will give it a try.

I tried a scissor linkage and now I see what you are talking about. The scissor linkage that I made stretched 333% whereas the stretch needed by the muscle is about 33%. The scissor does not change width much for a 33% change in length. Putting spacers between all the parallel linkages now makes a lot of sense to me. You could have got by using scissors if you went with a short muscle and long tendons, but that wouldn't look as realistic as your present scene.

Thank you!!
I really like the exchange of views and the dialogue that has formed between us!
Good day

Now I can go flex my scenes!

YEEES!!!
Flex everything !!
