I'm looking to solve the Schrödinger equation with a basis made of a tensor product of basis splines. A number of papers describe calculations made with a program designed this way, but they never describe how they got the knot sequence they use to define the basis.

How does one go about choosing a knot sequence for a set of B-splines to be used as a basis for the solution of a PDE?
