subroutine chooseclusternodes::clusterextrudedmesh

(

integer, dimension(:), optional, pointer

CFLayer)

Mark the strong connections based on the relative absolute magnitude of the matrix element.

Creates clusters of nodes using the given list of strong connections. Nodes assigned by the Passive vector may not be included in the clusters - others are ignored. The subroutine returns the vector CF which tells to which cluster each node belongs to.

subroutine chooseclusternodes::passiveextrudedmesh

(

)

Sets a marker for passive dofs everywhere else than at the top layer. This is intended for the hybrid method where a cluster is first made on a level and this is then inherited on the extruded levels.

subroutine chooseclusternodes::setparallelpassive

(

)

This subroutine sets nodes that are now owned by the partition to be passive before making the clustering. The idea is to communicate the clustering on parallel level based on the ownership.
