Hi, I downloaded the "ns_incom_inhom_2d_512-0.h5" from the link and tried using the data in my experiments. The data consists of four items, whose names and dimensions are:
Key=force, shape=(4, 512, 512, 2)
Key=particles, shape=(4, 1000, 512, 512, 1)
Key=t, shape=(4, 1000)
Key=velocity, shape=(4, 1000, 512, 512, 2)
I have several questions about them:
- what's the meaning of the first dimension of all data? E.g. t.shape=(4, 1000), I guess the '1000' means 1000 time steps, but the '4' is unclear.
- what do the 'velocity' and 'particles' mean? I guess the 'velocity' means the average velocity of the fluid in the grid, and the 'particles' means the average number of particles in the grid. Is it correct?
Thank you!
