Describe the issue

Hello,

I've tried to validate cache files using validate_cache.py

python validate_cache.py --config-path conf --config-name cached.yaml

I encountered the following error message:

===================================================================================

File "/workspace2508/physicsnemo/examples/cfd/external_aerodynamics/domino/src/validate_cache.py", line 122, in main

KeyError: 'neighbor_indices'

===================================================================================

I have validated the result keys and confirmed neighbor_indices are missing.

Available keys: dict_keys(['length_scale', 'surf_grid', 'sdf_surf_grid', 'surface_min_max', 'global_params_values', 'global_params_reference', 'geometry_coordinates', 'pos_surface_center_of_mass', 'surface_mesh_centers', 'surface_mesh_neighbors', 'surface_normals', 'surface_neighbors_normals', 'surface_areas', 'surface_neighbors_areas', 'surface_fields'])
Error executing job with overrides: []

====================================================================================
I use the following surface points sample in config.yaml file

surface_points_sample: 10_000 # Number of points to sample on surface per epoch

Minimum reproducible example
