Class
    Foam::searchableExtrudedCircle
 
Description
    Searching on edgeMesh with constant radius
 
    \heading Dictionary parameters
    \table
        Property    | Description                       | Required | Default
        type        | extrudedCircle                    | selector |
        file        | The name of the edge mesh         | yes   |
        radius      | Search radius around the edges    | yes   |
    \endtable
 
Note
    - The edge mesh file is to be located in the constant/geometry directory.
    - Can not be used with snappyHexMesh since only implements nearest
      searching.
 
Note
    Longer type name : \c searchableExtrudedCircle
