摘要:In this talk, we introduce an immersed boundary method to solve the stationary and non-stationary inextensible interface problems. The problem comes from the simulation of the vesicle dynamics in fluid flows. The scheme uses a linearly semi-implicit  discretization for the non-stationary Stokes part and we have proved that the spreading operator acting on the tension and the surface divergence operator acting on the velocity are skew-adjoint numerically so that the resultant matrix without bending is symmetric. Moreover, we can prove that the proposed immersed boundary scheme for non-stationary problem with bending is unconditionally energy stable.
