Keywords: kinetic scheme, gridfree, implicit

Lower-Upper Symmetric Gauss Seidel (LU-SGS) implicit method has been implemented within the framework of gridfree Least Squares Kinetic Upwind Method (LSKUM). The LU-SGS method is modified to preserve the generality of the gridfree method for non-symmetric connectivity and yet retain matrix-free feature of the LU-SGS method.
