# Volume Mesh
The volume mesh represents the discretized computational domain in Flow360, where fluid flow phenomena are numerically solved. This section covers the fundamental aspects of volume mesh handling and its components.
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
# Components
# Zones
Zones define distinct regions within the volume mesh, each potentially governed by different physical models.
# Boundaries
Boundaries define the physical and mathematical conditions at the edges of the computational domain.
