Is it my own or Mathcad 15 error?

Is it my own or Mathcad 15 error?

When I have 20 elements in vectors with operators (for parallel calculation of 4 curves) all is OK!

When I have 40 elements in vectors with operators (for parallel calculation of 8 curves) it is not OK!

See please attach!

My Mathcad Prime 4 is break when I open the converted 8-Flyers file!

Help please

I was already wondering why you have not posted these Platonic solids long ago 😉

Has this finish point in the tetrahedron a name?

If not - it is Werner point! 

I don't think that this point has any special meaning (its seems to be a bit lower than the center of mass). Different initial conditions (as to which point chases which with what velocity) may lead to different points.

Octahedron is easy and looks quite nice

Dodecahedron is a bit more complicated - her you see versions with 20 and with 18 moving points. I leave the Icosahedron with a max of 12 moving points up to you - have fun!

Wunderbar!

I have seen someone like this new math object

Here is the file.

Its still incomplete and eventually throws an error. It cannot handle multiple loops (like 1 chase 2, 2 chases 3, 3 chases 1 AND 4 chases   5, 5 chases 6, 6 chases 7). It cannot handle the case when one point is hunted by two different points, etc.

Also, as the file originally was not written for animations, the way i do those animations is rather crude, bold and inefficient. I was too lazy to write the necessary routines to create the data structure just once and pick up the necessary points for each animation frame. Instead the whole calc is done for every frame.

Feel free to make it more efficient and provide an animation for the icosahedron:

It is a diamond of our discussion!

Thanks for this gift to my 70-birthday - see please here

But the real gift is - to point on the error in my model!

HAPPY BIRTHDAY, Valery!!

С днем Рожденья, г-н профессор!

Вы так молодо пишете, не мог представить, что вам уже 70!

Счастья вам!

Пауль

спасибо!

Dear Valery Sorry I am a few days late: Hjertelig tillykke med de 70år. Gid du længe leve må. 生日快乐,福如东海,寿比南山 - and thanks for the flying bats.

опс

я на старости лет научился понимать по-датски

спасибо

One mathematics teacher (a women!) from the Air Force Academy found a mistake in my model!

See please the attach!
