Inter-Region Boundaries Have Same Perimeter Triangulation

In cases where the inter-region boundaries are not common but the perimeter triangulation is the same, follow the guidelines below to prepare the surface further:

  1. Combine boundaries that belong to the same inter-region interface together into one boundary. Repeat as necessary for all inter-region boundaries.

  2. Separate out each region either by using Create New Region from Boundaries or the Split Non-Contiguous region options, such that each region is composed of unique boundaries.

  3. Create an in-place interface between each boundary pair (Boundary 1 and Boundary 6 in the above example) and then proceed with the meshing process as normal.

In this instance, one of the boundary pairs that belongs to the interface will be deleted and a copy of the second boundary used for the meshing process, resulting in a conformal mesh at the inter-region boundary interface. The original import surface representation is left unaffected by this process.
