Patent ID: 8390620

Claim:
A computer implemented method of conforming an interface between a first mesh and a second mesh, the method comprising: identifying a first interface surface in the first mesh and a second interface surface in the second mesh residing along the interface, wherein the first and second interface surfaces are initially non-conforming along the interface; pairing chords within the first and second interface surfaces that fall within a threshold separation distance of each other; identifying unpaired chords within the first and second interface surfaces after pairing the chords that are within the threshold separation distance of each other; recursively inserting or extracting one or more sheets within one or both of the first or second meshes, wherein the sheets that are extracted each include one of the unpaired chords that reside within the first or second interface surfaces and the sheets that are inserted each include a chord that matches one of the unpaired chords, wherein the recursive inserting or extracting continues until all chords within the first interface surface are paired with corresponding chords in the second interface surface and all chords within the second interface surface are paired with corresponding chords in the first interface surface; setting a depth parameter in the first mesh indicating how many layers of elements within the first mesh changes are permitted; and performing column collapse operations within the first mesh to localize changes within the first mesh to within the depth parameter about the interface.
