**课程名称：** ICEMCFD 精通大师班（二级） **课程概述：** 该课程是关于计算流体动力学（CFD）中至关重要的网格生成技术。网格生成是将连续流场离散化为控制体的过程，直接影响CFD求解的准确性和稳定性。本课程旨在将您培养成为网格生成专家，能够高效地创建高质量网格，节省宝贵的项目时间。 课程将重点介绍两种主要的网格生成策略： * **全六面体网格（Hexa Meshing）：** 被誉为一项“艺术”，需要大量时间和技巧，但能提供最精确的解决方案。六面体网格具有节点数量少、计算资源需求低、求解时间短的优势，并能有效避免四面体网格中常见的数值扩散等问题。据估计，四面体网格的网格量可能是六面体网格的五倍。 * **四面体网格（Tetra Meshing）配合棱柱层（Prism Layers）：** 相对六面体网格，四面体网格生成更为便捷。 本课程将深入教授如何在 ICEMCFD 软件中进行复杂的六面体网格划分，涵盖诸如**圆形圆柱体、三维翼型、搅拌罐、风力涡轮机**等更复杂的几何结构。您将学习到关于CFD网格生成的所有“秘诀”和“技巧”，从而能够根据CFD仿真需求创建完美的网格，并在更短的时间内获得最精准的结果。此外，课程还将涵盖提升六面体网格效率的各种方法和主题。 **课程亮点：** * 提升在 ICEMCFD 中进行复杂六面体网格划分的技能。 * 掌握高效生成高质量网格的技巧，大幅缩短项目周期。 * 理解不同网格类型（六面体 vs. 四面体）的优劣及适用场景。 * 学习针对各种复杂几何体的网格划分策略。 * 获得在CFD网格生成领域的专业知识。 **目标人群：** 希望提升CFD网格生成效率和准确性的工程师、研究人员或学生。
Meshing is the most important part of any CFD process. Meshing is the process to divide continuous domain in discrete parts known as control volumes. After discretizing, this mesh is provided to numerical (CFD) solver to solve algebraic equations arising from partial differential equations of continuous domain. Therefore meshing is most important part of any CFD process and accuracy & stability of CFD process largely depends on good quality mesh. It is estimated that around 70% time is spent on meshing in any CFD project. But after taking this course, you will be expert in meshing and you can generate meshes in very less time than rest of CFD community. In meshing you can either go with full hexa meshing or tetra meshing (with prism layers). Hexa meshing is more of an art and requires great deal of time. But yields most accurate solution. It also requires less number of nodes and hence it require less compactional resources and less solution time. It also avoids numerical errors /numerical diffusivity as you can observe in tetra meshes. It is estimated that tetra meshes requires as much as five times of mesh size as that of hexa meshing. In this course you will enhance your ICEMCFD hexa meshing skills on more complicated geometries such as circular cylinder, 3D airfoils, stirred tank, wind turbine etc. Here you will each and every trick/tip of business of CFD meshing. After going through this course, you will be able to create perfect grid according to CFD simulation requirements and hence will be able to get most accurate results in less time.We will cover different topics as well which will increase effectiveness of hexa meshing.
