Coreform Cubit 2024.8 User Documentation
In addition to finding mesh intersection , Coreform Cubit can also remove mesh intersection by slightly repositioning the nodes of intersecting elements. Nodes are moved along surface normals just enough so that the intersection is zero or undetectable. The command syntax is:
Remove Mesh Intersection {Block|Body|Volume} <id_list> [with {Block|Body|Volume} <id_list>] [low <value=0.0001>] [high <value>] [detail]
The low and high options set how much cumulative intersection should be detected. A low value of 0.1 would ignore elements that do not intersect more than 10% of their volume. Similarly, a high value of 0.5 would discard elements that intersect more than 50% of their volume. Both low and high can be used simultaneously. The default for the low value is 0.0001
The detail option provides information, printing the
ten nodes moved the largest distances, providing users an idea of the
greatest changes in the mesh.
Largest node movements: Node 165 moved a distance 0.003889 Node 170 moved a distance 0.003886 Node 1091 moved a distance 0.003861 Node 163 moved a distance 0.003832 Node 1100 moved a distance 0.003794 Node 1090 moved a distance 0.003739 Node 1101 moved a distance 0.003728 Node 117 moved a distance 0.003701 Node 164 moved a distance 0.003672 Node 121 moved a distance 0.003483
