本课程主要介绍计算地球物理的基本方法和工具,旨在让学生掌握基本的计算地球物理方法,能够采用有限差分来实现波动方程、扩散方程的数值模拟,并对计算结果进行分析。同时,本课程注重学生的动手能力,要求学生能够随堂进行基本的Jupyter Notebook文字化编程。

本课程主要介绍有限差分和伪谱法等数值求解方法,并分别介绍椭圆型、抛物型和双曲型偏微分方程的数值计算方法。此外,本课程还将简单介绍基于OpenMP、MPI和CUDA并行的地球物理高性能计算方法。

本课程将会教学生使用Linux操作系统,并采用Anaconda进行Python环境进行管理,使用Jupyter Notebook作为Python的IDE进行文字化编程,安装并使用Madagascar开源地球物理平台。开源软件和开源研究将贯穿本课程的所有内容,鼓励学生进行开源研究探索。
