The Bessler Wheel, mystery solved.

[Pirate88179]

Why would he have to simulate it using software if he already has a working wheel as he has claimed?  He claims it works so, no simulation needed.  Of course, I still have my doubts about this.

Yeah I just contacted my reseller now for a student version of dynamics for my spaceclaim

I will crush the figures of gurangax the retarded.

My design is a mirror mirrored hehe, balanced and strong

2d vs 3d question;

I think the Grurangax should consider gaining access to a student version
of a professional package of a 3d drawing and 3d mechanical simulation
computer software. He may have to become a "virtual" student to do it and to get
access to a low cost student version of the software. This is especially true
if he has end-to-end confidence in his design. Hopefully this software would
come with an "evolutionary" design simulator that would allow computer
driven experimental parameter adjustment of subsystems. This type of method
would save time, especially in the worst case should his methods fail to converge
to a solution...

There is absolutely no point in simulating this (or any similar mechanism) using  engineering software and expecting to find an over-unity or self running result.

All such simulations have conservation of energy and momentum built in to equations of motion. If they show an over unity result then this is simply an artefact of the method of calculation and is incorrect.

In case you hadn't realised these principles ABSOLUTELY PRECLUDE any device from being a self runner. It simply does not matter what geometry you come up with.

What would be the point of modelling a device such as this when you already know the result will show that it does not work?

Except for one thing. Gurangax has already created several perpetual motion machines in wm2d, which seems to contradict your point:

I think this guy has discovered a very interesting principle here.  I would like to see a real live running wheel taking advantage of it, though.

Your obviously failed to note my point that:

"If they show an over unity result then this is simply an artefact of the method of calculation and is incorrect."

Many simulations use numerical methods to approximate solutions to systems of partial differential equations.
Depending on the problem at hand these equations can become unstable depending on the starting conditions and may not always converge smoothly on a solution.

In this situation the numerical approximation to a system that would be conservative if it could be solved implicitly may give a non conservative result when solved numerically.

Most simulation software seeks to minimise such behaviour. However, depending on the accuracy and computation intensity desired the design of the simulation algorithm may allow some degree of 'non physical' results.
