报告摘要:
This talk develops the finite volume element method in Arbitrary Lagrangian-Eulerian framework (ALE-FVEM) for the time-dependent convection-diffusion problem on moving domain. We present two fully discrete schemes based on the conservative ALE form of the equation, where the implicit Euler method and geometric conservation laws (GCL) are utilized. The stability and error estimates of the two fully discrete schemes are proved for the first time, and the scheme satisfied the GCL is a better choice for long time problem. Finally, some numerical experiments are provided to confirm the theoretical results.
