报告题目:Stability and error analysis of IMEX SAV schemes for the magneto-hydrodynamic equations
报 告 人:李晓丽教授
报告摘要:In this talk, we shall first construct and analyze first- and second-order implicit-explicit schemes based on the scalar auxiliary variable approach for the magneto-hydrodynamic equations. These schemes are linear, only require solving a sequence of linear differential equations with constant coefficients at each time step, and are unconditionally energy stable. We derive rigorous error estimates for the velocity, pressure, and magnetic field of the first-order scheme in the two-dimensional case without any condition on the time step. Numerical examples are presented to validate the proposed schemes. Next we develop a numerical scheme based on the truly consistent splitting approach in time and the MAC discretization in space for the time dependent Stokes equations, and establish first-order in time and second-order in space error estimates for velocity and pressure in different discrete norms.
