Abstract
A coupling analysis of thermal convection problems is performed in this work. By approximating the material derivative along the trajectory of fluid particle, the characteristic curve (CC) method can be considered. The most attractive advantage of this method is the symmetry of the linear system, which enables some classic symmetric linear iterative solvers, like the conjugate gradient (CG) method or the minimal residual method (MINRES), to be used to solve the interface problem of the domain decomposition system. Applications to industrial problems are demonstrated to show the effectiveness of our approach.
