[MOAB-dev] Failed to rebuild obb trees!

[Paul Wilson]

Hello Lukasz,

We may need to revisit some of the logic of the Cub file reader.  These errors imply that MOAB is attempting to process a geometry representation in addition to the mesh representation.

Prior to more testing, I can't tell if this is because:

a) Your options don't request that the geometry representation be loaded from the file, but MOAB tries to process the geometry anyway, or

b) The geometry representation is being loaded (although I think your choice of options should be preventing that), and the presence of sheet bodies in your model is causing the geometry processing to fail.

I'll see if I can get someone to confirm which of these situations it is (or perhaps something else) so that we can determine how to resolve it.

Paul

Hello,

I have a strange problem with the reading file test_mesh_cut.cub. Mesh is ok, I can process it. The issue is with the error.

Code:

    const char *option;
    option = "";
    moab.load_file(mesh_file_name, 0, option);

Is this problem with the file or something related to a cubit. The problem appears for v5.1, for older versions seems to be ok.

Regards,
Lukasz
