The SOLA (solution algorithm) method is one of the most widely used methods for analyzing incompressible viscous flows. However, this method often requires a number of iterations to obtain a converged solution for a practical problem on transient flow. Hence, a theoretical analysis of this method was carried out in the present study to clarify the reason why this method can give converged solutions. It was proved that the SOLA method is identical to the SMAC (simplified marker and cell) method in the interior cells of the computational domain. On the other hand, it is not identical to the SMAC at the cells adjacent to the boundary cells. Hence, a modified SOLA method which improves the computational efficiency was developed by taking into account boundary conditions in the iteration process. It was demonstrated that the modified SOLA could analyze transient flow more efficiently than the original SOLA.
