@syn_burz I got no output and no message about the kernel, although it was obvious that the kernel had crashed. I'm using Maple 17, 64-bit, Windows 8.

What should the output be if the number is 26 and the prime is 3?

@cskoog Thanks. I posted my Reply primarily to find out what you just said.

Check the results of command kernelopts(version).

@Markiyan Hirnyk It would be useful, as a first step to the 3D goal, to have a canonical ordering of the vertices, edges, or faces of polyhedra.

Please re-run the command without the 'evaluate' option and post the results. If the code contains large matrices, please reduce them to 2x2 examples.

 Your initial conditions contain

ur(e,0)=1/ch(e)

What is ch? Do you mean cosh? 

If I change it to cosh, I still get an error, but it's a different error with a more-informative message. But I am not pursuing that error any further unless you say that cosh(e) is what you meant.

@emma hassan Sorry, I don't know enough about finite difference solutions to PDEs to help you anymore with this.

@Alejandro Jakubi 

Is that replacement of the print/foo mechanism by a "PrintTools" package an expresion of desire or work in progress?

It may not be fair or polite to ask the scientists, in a public forum, about works in progress. They may be contracturally required to give no answer either way, and then they feel bad for seeming impolite by ignoring you.

@User716 In my opinion, one usually finds that eval is ultimately easier to use than assign in most cases, even though assign often initially seems to be the easier one. This is even more true in a loop.

@emma hassan Make i= 0..M. If I do this, it runs fine, and I get a list of purely numeric points.
