# Volume Mesh
The volume mesh represents the discretized computational domain in Flow360, where fluid flow phenomena are numerically solved.
A volume mesh in Flow360 consists of three-dimensional elements that discretize the computational domain. The mesh structure is defined by:
- Zones: Distinct regions within the volume mesh, each potentially governed by different physical models
- Boundaries: Surfaces that define the edges of computational domains and interfaces between zones
# Mesh Requirements
Flow360 supports unstructured volume meshes with the following element types:
- Tetrahedrons
- Hexahedrons
- Prisms
- Pyramids
