get_odd_parity_from_basis_function_name Function

private function get_odd_parity_from_basis_function_name(name) result(is_odd)

This relies on the behaviour of the basis functions. If a variable needs to be zero, then this is done by forcing the basis functions on that edge to zero. For both left and right edges the quadratic basis functions have a non-zero entry in their even rows/columns, whereas the cubic basis functions have a non-zero entry in their odd rows/columns. Concrete: - cubic, left: C2 is non-zero, zero out elements with spline(2) - cubic, right: C1 is non-zero, zero out elements with spline(1) - quad, left: Q4 is non-zero, zero out elements with spline(4) - quad, right: Q3 is non-zero, zero out elements with spline(3) See also ordening of a quadblock in mod_build_quadblock.
