Mechanical applications

[ynedelec3]

Though I don't have present projects dedicated to a use of Irritator I explore potential mechanical applications and possible collaborations within that scope, which seems different to the domain covered by examples.

I produced a bouncing-ball model with qss1 (screenshot attached), as a prospective idea.

Within that scope and based upon bouncing masses, there is an interesting mathematical evaluation of Pi with a mechanical similitude, which could be interesting to reproduce and would allow to inspect model accuracy. Article is linked below.

If this seems of any interest...-)

This model cannot stop the ball, it reaches a non-physical periodic regime at the end of the bounded total bouncing time (then the counter becomes linear with time as can be seen on figure).

I had to multiply ball location by -1 to compare with threshold, the computation session launched by "Simulation run one" automatically selects "Up detection" (a bug ?)

I create an issue for the Up detection bug. Thx.

Bad behaviour of "Up detection" is fixed by this commit but negative multipliers remains necessary to simulate adequate bounces. I guess I misunderstand the role played by "Up detection"...
