Tailoring Unstructured Meshes for Use with 3D Co-Volume Methods for Engineering Analysis

随着计算流体力学和计算电磁等领域技术的快速进步，计算技术变得越来越重要。多年来，已经发展了各种方法来求解控制方程。最有效的技术需要对领域进行结构化细分。这通常会将问题限制在简单的几何图形上。非结构化网格提供了模拟各种工业问题所需的几何灵活性。然而，涉及工业感兴趣的几何形状的模拟在CPU时间和内存需求方面都对当前的计算资源提出了严格的要求。本提议旨在开发一种新的网格划分技术，该技术能够在非结构化网格上使用协体积解格式，从而保持基于结构的求解算法的效率和复杂工业几何形状的非结构化细分的灵活性。

Computational techniques have become increasingly important with the rapid advancements in technology in areas such as computational fluid dynamics and computational electromagnetic. Over many years, various approaches have been developed for the solution of the governing equations. The most efficient techniques require a structured subdivision of the domain. This normally constrains the problem to simple geometries. Unstructured type meshes provide the geometrical flexibility necessary for simulating the full range of industrial problems. However, simulations involving geometries of industrial interest can be expected to place severe demands on current computational resources, in terms of both cpu time and memory requirements.The present proposal aims at developing a new meshing technique that enable the use of co-volume solution schemes on unstructured meshes, hence, maintaining the efficiency of the structured based solution algorithms and the flexibility of the unstructured subdivision of complex industrial geometries.
