Validation errors when loading general meshes with rx.validate(): input requirements and possible fixes

[will-zzy]

I encountered validation errors when calling rx.validate() after loading a general mesh with RXMesh. For example:

[14:20:26] RXMesh: Line 2643 File /home/zzy/engineer/rxmesh_wsl/rxmesh/include/rxmesh/rxmesh_dynamic.cu
[14:20:26] RXMesh: RXMeshDynamic::validate() check_num_mesh_elements failed
[14:20:26] RXMesh: Line 2664 File /home/zzy/engineer/rxmesh_wsl/rxmesh/include/rxmesh/rxmesh_dynamic.cu
[14:20:26] RXMesh: RXMeshDynamic::validate() check_ribbon failed
[14:20:26] RXMesh: Line 427 File /home/zzy/engineer/rxmesh_wsl/rxmesh_binding/csrc/rxmesh_wrapper.cu
[14:20:26] RXMesh: RXMesh validation failed for mesh
[14:20:26] RXMesh: Line 2976 File /home/zzy/engineer/rxmesh_wsl/rxmesh/include/rxmesh/rxmesh_dynamic.cu
[14:20:26] RXMesh: RXMeshDynamic::update_host error in updating host. m_num_vertices 12998 does not match m_h_vertex_prefix calculation 12997

I would like to understand what requirements RXMesh imposes on input mesh files. Is it possible to resolve these issues using RXMesh’s own kernels, or should the mesh be preprocessed beforehand?
