Rib Detection
Maximum Elements in Rib Specifies the maximum number of elements that can be present in a group for the software to consider the group a rib. The software does not consider element groups that contain more elements than this value as ribs.
Maximum Rib Area Specifies the maximum area for a rib. The software only considers groups of elements that have an area less than this value as ribs.
Minimum Percent of Rib Boundary Nodes Lets you specify the minimum percentage of nodes that can be located along the outer edge of a rib. The software computes the total number of nodes in the entire rib, as well as the total number of nodes along the edges of the rib. If the percentage of nodes along the edges of the rib is smaller than this value, the software does not add the elements to the Rib List.
