AI中文摘要:
我们分析了一种用于求解变形域上含时对流扩散方程的时空可杂交间断Galerkin方法。通过使用加权测试函数,我们证明了该离散格式在对流占优情形下的稳定性,并推导了先验时空误差估计。一个数值算例验证了上述理论结果。
英文摘要:
We analyze a space-time hybridizable discontinuous Galerkin method to solve the time-dependent advection-diffusion equation on deforming domains. We prove stability of the discretization in the advection-dominated regime by using weighted test functions and derive a priori space-time error estimates. A numerical example illustrates the theoretical results.
