Check overlap

Request Netgen overlap checking during mesh generation.

Location

Mesh → Free Tetrahedral → Check overlap

Initial value: true.

This boolean enables the native overlap check; it does not repair overlapping geometry or define a physical contact interface.

Using the value

Review overlaps and intended domain interfaces before Build Mesh; leave checking enabled when appropriate for your geometry workflow.

Troubleshooting

If the check fails, inspect the intersecting solids and geometry operations. Resolve unintended intersections before meshing.
