This Custom Block filters out a point map by excluding the result of the points in the vicinity of mesh boundaries.

Used to filter out stress concentrations that appear on boundaries, which are typically simulation artifacts rather than real structural hotspots.
Uses the Keep Out Distance (KO Distance) to define a buffer zone around the mesh boundaries — any points within this distance are excluded from the output point map.

Name	Type	Description
`Point Map`	Scalar Point Map	Point Map
`Mesh Entities`	list<mesh>	Mesh entities
`KO Distance`	Scalar	Keep Out Distance - The distance around the mesh elements
`Region`	Choice	The region you want to filter — `Outside` keeps points with distance > KO Distance, `Inside` keeps points with distance < KO Distance, `Boundary` keeps points with distance = KO Distance
