How Mesh Generation Procedure Works?

Posted by on

Mesh generation is the process of creating polyhedral or polygonal mesh that is typically approximate to a geometric domain. The application of mesh generation encompasses rendering to physical or computer simulations such as Computational Fluid Dynamics or Finite Element Analysis.

How Mesh Generation Procedure Works?

The input model for mesh generation can vary but there are certain common sources such as B-rep, NURBS, CAD, and STL. The domain is highly interdisciplinary in nature, with significant contributions in computer science, mathematics, and engineering. Once the input source for mesh generation is available, the steps follow as below:

1.Specify the mesh size – First of all, it is important to choose the shape of the object or mesh, and specify the type of element as well. This helps the designers and engineers to know specifically what you are looking for.

2.Create 1D mesh – Next, create mesh in one-dimension, on all the boundary edges.

3.2D mesh generation – Once 1D mesh has been created, it is important to generate 2D mesh and then choose mesh algorithm. Create two-dimensional mesh on all the boundary edges.

4.3D mesh generation – Complete creating 2D mesh and from that generate 3D mesh in internal space.

So, this is how mesh generation process typically works, first creating 1D meshes and gradually moving forward towards generating 2D and 3D mesh from it eventually. 1D and 2D meshes are created on the boundary edges, while 3D mesh generation occurs in the internal space. The final 3D output is used in different applications across different industries.
