Two-Dimension Meshing and Elements

Introduction

Two-Dimension Meshing and Elements are fundamental aspects of Computer Aided Engineering (CAE). Meshing is the process of dividing a geometric space into a discrete number of finite elements. These elements are used to solve complex engineering problems using numerical methods such as Finite Element Analysis (FEA).

Comparison Between Tria and Quad Elements

Tria and Quad are two common types of elements used in two-dimension meshing. Tria elements are triangular, while Quad elements are quadrilateral. Both have their advantages and disadvantages, and the choice between them depends on factors such as mesh density, computational efficiency, and application-specific considerations.

Quality Checks in Two-Dimension Meshing

Quality checks are essential in two-dimension meshing to ensure the accuracy and reliability of the results. Key quality checks include mesh density, aspect ratio, skewness, orthogonality, and mesh biasing in critical regions.

Analogy

Think of two-dimension meshing like cutting a pizza. The pizza is the geometric space, and each slice is a finite element. Just like how the size and shape of each slice can affect how much pizza you get, the size and shape of each element can affect the accuracy of the engineering analysis.
