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

Disable the global assignment of 500 to FRAME before you begin the animation and both the 4- and 8-flyers work ok. (The MC15 ones that is;  I don't know about the Prime file).

I dont't experience any errors when I open your 8-flyer files.

Both the Mathcad 15 and the Prime file seem to work OK and show the plots.

Can you be more specific about what is not OK and what is broken?

Here is what I see in MC15

Thanks Alan and Werner!

8 bats fly out of cube tops. They fly in pairs against each other 1->2, 2->6, 6->7, 7->3, 3->4, 4->8, 8->5 and 5-1 (see the picture). The model with 4 bats works without errors. In the Model with 8 bats - the wrong answer. This is my mistake or mistake Mathcad. May be Mathcad can work with 20 operators in the vector and cannon works with 40 ones!

Still not clear to me what you think that is going wrong.

But the question is still left!

Is it my own or Mathcad 15 error?

I guess its not Mathcad but the way you had setup the problem.

There sure should no points go outside the tetrahedron.

I digged into my archive and found an old sheet were I played around with a similar "problem" and quickly adapted it to your scenarios. Here's what I see:
