The present study describes a novel approach treating freshly cleared cells when simulating incompressible flows using the immersed boundary method. The method calculates material derivative in Lagrangian coordinate system to approximate the solution at the freshly cleared cells. In this study, we use a simple test case to compare our proposed method with the commonly used one-dimensional interpolation method in the Eulerian coordinate system.
