#### Mesh.volume\_mesh(volume\_fill\_type=VolumeFillType.TET, quadratic=False, prism\_layers=None, prism\_surface\_expression='\*', prism\_volume\_expression='\*', growth\_rate=1.2, scope=)

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.
