#### Mesh.volume\_mesh(volume\_fill\_type=VolumeFillType.TET, quadratic=False, prism\_layers=None, prism\_surface\_expression='\*', prism\_volume\_expression='\*', growth\_rate=1.2, scope=&lt;ansys.meshing.prime.lucid.scope.VolumeScope object&gt;)

Generate a volume mesh on the model.

**Parameters:**

**volume\_fill\_type**

Type of volume elements to generate.

**quadratic**

Whether to generate a quadratic mesh. The default is `False`. A quadratic mesh is not supported with parallel meshing. It is only supported with a pure tetrahedral mesh.

**prism\_layers**

Number of prism layers to grow. The default is `None`. If a value for prism layers is specified, prism layers are generated.

**prism\_surface\_expression**

Face zones or TopoFaces to grow prisms from. The default is `"*"`, in which case prisms are grown from all surfaces.

**prism\_volume\_expression**

Volumes or TopoVolumes to grow prisms in. The default is `"*"`. This expression evaluates to zone names and volumes, or TopoVolumes are queried based on the zones evaluated.

**growth\_rate**

Prism growth rate. The default is `1.2`.

**scope**

Scope of volumes to mesh.
