spongeLayer_plane_polyn6_for_treeids Function

private function spongeLayer_plane_polyn6_for_treeids(me, treeIds, tree, n) result(res)

This function calculates the sigma for the spongeLayer from treeid for the polynomial order n6. Sponge profile: where, \sigma_A - sponge strength, L - thickness, x0 - start of sponge.
