`rblock.facet.centroid`

Syntax

- v = rblock.facet.centroid(p,if)
Get the facet centroid. if can take values from 1 to

`rblock.facet.num`

. The facets correspond to the entries returned by`rblock.facet.map`

and`rblock.vertex.map`

.Returns: v - facet centroid vector

Arguments: p - rigid block pointer

if - facet number

Component Access

f = `rblock.facet.centroid`

(p, if)`->x`

- f = rblock.facet.centroid.x(p,if)
Get the \(x\)-component of the facet centroid. if can take values from 1 to

`rblock.facet.num`

. The facets correspond to the entries returned by`rblock.facet.map`

and`rblock.vertex.map`

.Returns: f - \(x\)-component of the facet centroid vector

Arguments: p - rigid block pointer

if - facet number

Access other vector components (\(y\), \(z\) (*3D ONLY*)) by substituting the component name where \(x\) appears above. See Member Access Operator for information about accessing members from data types using `->`

.

Deprecated Component Access

Component access by adding an optional integer in the function arguments (e.g., `f = rblock.facet.centroid(p, 1, 3)`

) is deprecated. It remains available but will not be supported in future versions. See Component Access with Integers in FISH on the Deprecated Commands and FISH page for details.
