标题： PySEMTools: A library for post-processing hexahedral spectral element data

摘要： PySEMTools 是一个基于Python的库，用于处理用高阶六面体单元在计算流体力学中使用的谱元方法生成的模拟数据。它旨在最小化分析大型文件时通常需要的中间步骤。具体来说，是在后处理时使用独立代码库（如求解器本身）的需求。为了实现这一效果，我们利用消息传递接口（MPI）进行分布式计算，以在谱元网格上执行典型的数据显示任务，如谱准确的微分、积分、插值和降阶建模等。所有功能都以独立的Python代码形式提供，并且不依赖于特定求解器的使用。我们相信 `PySEMTools` 为研究人员提供了加速科学研究和降低在计算流体力学中使用高级方法的入门门槛的工具。 显示英文摘要

摘要： PySEMTools is a Python-based library for post-processing simulation data produced with high-order hexahedral elements in the context of the spectral element method in computational fluid dynamics. It aims to minimize intermediate steps typically needed when analyzing large files. Specifically, the need to use separate codebases (like the solvers themselves) at post-processing. For this effect, we leverage the use of message passing interface (MPI) for distributed computing to perform typical data processing tasks such as spectrally accurate differentiation, integration, interpolation, and reduced order modeling, among others, on a spectral element mesh. All the functionalities are provided in self-contained Python code and do not depend on the use of a particular solver. We believe that `PySEMTools` provides tools to researchers to accelerate scientific discovery and reduce the entry requirements for the use of advanced methods in computational fluid dynamics.
