Increase the resolution of the grid
Hello, I want to try to increase the resolution of the grid to realize the representation of more detailed objects, but I have a problem, how can I solve it? Have you ever tried to improve the grid resolution?
I tried to change pg_scale = [1000, 2000, 4000]to pg_scale= [1000, 2000, 3000,4000] ，and then encountered an error：

I'm not sure about this error.
The simulation part may be too slow if you double the resolution.
This problem happens here：
self.from_torch(particles.data.cpu().numpy(), features.data.cpu().numpy(), velocities.data.cpu().numpy(), particle_rho.data.cpu().numpy(), particle_mu.data.cpu().numpy(), particle_lam.data.cpu().numpy())
Have you ever tried to improve the grid resolution?
