viscSpongelayer_radial_for_coord Function

private function viscSpongelayer_radial_for_coord(me, coord, nDim, n) result(res)

This function calculates the sigma for the radial viscosity spongelayer for 2D and 3D, and multiply with targetState. This function is currectly used to define viscosity sponge in musubi.
