| Abstract: | Multimedia interfacial computation is a very important problem in numerical simulations of multimedia fluid dynamics.The RKDG finite element methods over unstructured meshes are applied to give an computing method for capturing multimedia interfaces by solving the level set equation and reinitializing equation.Numerical results show that the RKDG finite element methods have the advantage of computing the multimedia interfaces over unstructured meshes. |
