Problems with open surfaces

I'm using a level set function of an **open** surface and I want to use VolumeToMesh to get an adaptively mesh, but the algorithm creates self intersecting triangles in all cases.

does Openvdb work correctly only with closed surfaces?

Start with the VolumeToMesh path and reproduce the reported self-intersecting triangles using a level set for an open surface. Read the surrounding OpenVDB volume-rendering and meshing behavior to determine whether open surfaces are supported; done means the behavior is corrected or the supported-surface limitation is clearly established.
