Mesh generation is the practice of creating a mesh, a subdivision of a continuous geometric space into discrete geometric and topological cells.Often these cells form a simplicial complex.Usually the cells partition the geometric input domain.Mesh cells are used as discrete local approximations of the larger domain. Meshes are created by computer algorithms, often with human guidance through a GUI , depending on the complexity of the domain and the type of mesh desired.A typical goal is to create a mesh that accurately captures the input domain geometry, with high-quality (well-shaped) cells, and without so many cells as to make subsequent calculations intractable.The mesh should also be fine (have small elements) in areas that are important for the subsequent calculations.

  • 計算格子(英: computational mesh/grid)または単に格子とは、数値解析における離散化のために用いられる、解析領域(2次元または3次元の幾何形状)を有限個に分割した部分領域のことである。構造解析分野では要素とも言う。 計算領域を格子に分けることを格子生成(英: mesh generation)または格子分割と言う。 各計算格子は番号付けにより識別され、その幾何学的形状は節点(nodes)の座標値により規定される。また、節点には要素節点番号と呼ばれる要素内での節点の番号を付ける。 (ja)

  • Geração de malha (em inglês: mesh generation ou grid generation) é a prática de gerar uma malha poligonal ou poliédrica que se aproxima de um domínio geométrico. Os usos típicos são para renderização em uma tela de computador ou para simulação física, tais como no método dos elementos finitos ou dinâmica dos fluidos computacional. A forma do modelo de entrada pode ser bem variada, mas as fontes comuns são desenho assistido por computador (CAD), NURBS, (B-rep), ou uma nuvem de pontos. O campo é altamente interdisciplinar, com contribuições encontradas em matemática, ciência da computação e engenharia. (pt)
