I think I have figured out a way to obtain perpetual motion using double cones. I need a software to test my theory. Is there any software out there than can test complex design integrating gravity and friction, some kind of dynamic CAD.

I will appreciate any help or advise.

A perpetual motion machine is, by definition, a machine which creates energy, i.e. puts out more energy than is put into it. If you're going to try to make one using a mechanical device only then its impossible to do. This is a fact which is directly derivable from Newton's laws. If you plan on doing it in any other way then its impossible from the law of conservation of energy. And believe me when I say that people have been trying, and failing, for well over 100 years.

Double cones apparently running up an inclined track is a neat illusion, found in science museums all over the world. The center of gravity of the double cone actually falls. If you put the whole assembly on a horizontal table, the rotor doesn't move.

The horizontal method works, the tracks are placed in a circular pattern, perpetual motion is achieved but no usable energy is obtained, the double cone just rolls around and around. My idea places the tracks in a vertical plane and uses gravity to obtain some torque. I tried building one but it got to large and cumbersome to build at home, hence I need some kind of dynamic CAD to test my theory, don't want to waste to much energy and time building a model, just in case its a flop:-)
Its just a thought, all ideas are built that way.

Any such software would have the current laws of physics built in, so it would not give the answer you are looking for.
As has been said above, these mechanisms don't produce more energy than put in.

Even the universe isn't a perpetual motion machine. It will eventually run out of usable energy. So what makes you think you can defy that?

Its not defying the laws of physics but manipulatiing gravity, you don't allow it to have a sweet spot and come to rest. I have achieved perpetual motion using these double cones, I have placed the tracks in a circular pattern. The problem is it cannot provide useful energy, it might push out a few milliwatts, that's free energy.

I think manipulating gravity is a poorly thought out phrase.

A few mill watts is free energy.

As I stated above its a well known fact that a perpetual motion machine cannot be created. Its not even that difficult to prove if you know calculus and Newton's laws.

" I need a software to test my theory. Is there any software out there than can test complex design integrating gravity and friction,"
Yes.
Software is available that will let you do this test.
What you need is a web browser, then you can post the idea on discussion fora and people will point it that it can't work.

So, you now have an answer to your  original question, and you know that your design won't work.
