Detailed Description

A sampledSurface defined by a surface of iso value. It only recalculates the iso-surface if time changes. To be used in sampleSurfaces / functionObjects.

Usage

Example of function object partial specification:

surfaces
{
    surface1
    {
        type     isoSurface;
        isoField T;
        isoValue 373;
        isoMethod topo;
    }
}

Where the sub-entries comprise:

Property	Description	Required	Default
`type`	isoSurface	yes
`isoField`	field name for obtaining iso-surface	yes
`isoValue`	value of iso-surface	yes
`isoValues`	values for iso-surfaces	yes
`isoMethod`	Iso-algorithm (cell/topo/point)	no	topo
`average`	cell values from averaged point values	no	false
`bounds`	limit with bounding box	no
`zone`	limit to cell zone (name or regex)	no
`zones`	limit to cell zones (names, regexs)	no
`simpleSubMesh`	Simple sub-meshing in algorithm itself	no	false
`exposedPatchName`	name for zone subset	optional
`regularise`	point snapping (bool or enum)	no	true
`triangulate`	triangulate faces (if regularise)	no	false
`mergeTol`	tolerance for merging points	no	1e-6

Some options are limited to particular algorithms.

triangulate is topo-only
simpleSubMesh and multiple isoValues are not available for point.

Note: For the isoMethod point should use a "cellPoint" sampleScheme since the triangles generated with this algorithm span across cells.
