A viscous correction on LU-SGS method is applied to improve the stability and efficiency for incompressible viscous flows with pseudo compressibility. It is implemented by stability analysis considering the contribution of the viscous jacobians. Numerical examples show that the present method is robust and efficient for low Reynolds number flows.
