| + | Because of the temporal and special derivatives, we couldn’t use a classic matlab solver to solve this set of equations. The approximation we used consisted in dividing the space into a grid: | ||

By using the same approximation on y<SUB>i</SUB>, and assuming that l<SUB>y</SUB>=l<SUB>x</SUB>, and that we have the same number of points of discretization, we get: | ||
