Mesh generation is the process of creating a mesh, which is a collection of interconnected elements used to represent a geometric shape or physical domain. This technique is essential in fields like computational fluid dynamics and finite element analysis, where complex shapes need to be analyzed or simulated. The mesh consists of nodes and elements, allowing for numerical methods to solve equations related to the physical phenomena being studied. There are various methods for mesh generation, including structured, unstructured, and hybrid approaches. Structured meshes use a regular grid pattern, while unstructured meshes allow for more flexibility in representing complex geometries. The choice of mesh type can significantly impact the accuracy and efficiency of simulations, making effective mesh generation a critical step in computational modeling.
