AI总结:

本文针对扩散-对流-反应问题,提出采用连续内部惩罚(CIP)稳定化的虚拟元方法,以在对流占优情形下获得准鲁棒格式,并通过数值实验验证了理论分析结果。

摘要:

本文考虑了扩散-对流-反应问题的虚拟元方法。为了在对流占优区域中也能设计出准鲁棒的格式,采用了连续内部惩罚(CIP)方法。由于虚拟元方法中典型的多项式投影算子的存在,稳定性和误差分析需要特别小心,尤其是在处理对流项时。文中给出了一些数值实验来支持理论结果。

英文摘要:

The Virtual Element Method for diffusion-convection-reaction problems is considered. In order to design a quasi-robust scheme also in the convection-dominated regime, a Continuous Interior Penalty approach is employed. Due to the presence of polynomial projection operators, typical of the Virtual Element Method, the stability and the error analysis require particular care, especially in treating the advective term. Some numerical tests are presented to support the theoretical results.
