# Volumes

*Volume entities in Flow360 are used to define regions for volume zones, local refinements, and 3D physics models. Flow360 provides six volume types that can be used individually or combined to create complex geometric configurations.*

## Contents

| *Volume Type* | *Description* |
|---------------|---------------|
| [**Box**](./00.box.md) | Rectangular prism defined by center, size, and orientation |
| [**Cylinder**](./01.cylinder.md) | Cylindrical volume defined by axis, radius, and height |
| [**Sphere**](./04.sphere.md) | Spherical volume defined by center and radius |
| [**Axisymmetric volume**](./02.axisymmetric-volume.md) | Body of revolution defined by a profile curve |
| [**Custom volume**](./03.custom-volume.md) | Volume zone defined by its enclosing surfaces |
| [**Seed point volume**](./05.seed-point-volume.md) | Volume zone defined by one or more interior seed points |

You can toggle volume visibility by clicking the eye icon that appears when hovering over or selecting the volume.
