Hi, and welcome to yt! Thanks for opening your first issue. We have an issue template that helps us to gather relevant information to help diagnosing and fixing the issue.
I just figured out that this error will be solved if I change the left_edge` and right_edge to a broader value.
Hi, everyone! I am trying to project gas particles (SPH) to a mesh in the octree structure. The particle data contains several np.array: particle_position: (n, 3) array where n=5303345 is the number of particles particle_density: (n, 1) array I use the following code to do this job: particle_ds=yt.load_particles(particle_data) gas_ds.add_sph_fields() # to generate the fields of (‘io’, ‘smoothing_length’) and (‘io’, ‘density’). add_sph_fields only iterates 5303342 steps
right_edge=[xxx,xxx] left_edge=[xxx,xxx] particle_oct=particle_ds.octree(right_edge=right_edge,left_edge=left_edge,n_ref=10) ######################################## Then, I would like to access some fields of
particle_oct
: cell_density=gas_oct[‘io’, ‘density’] ######################################## This raise the following error:IndexError: boolean index did not match indexed array along dimension 0; dimension is 5303342 but corresponding boolean dimension is 5303345
######################################## How do I fix this error and get the correctgas_oct[‘io’,‘density’]
?
