Availability of data for Navier-Stokes

[scaomath]

Hello, in the Navier-Stokes DeepONet model: https://github.com/Zhengyu-Huang/Operator-Learning/blob/b7c484150fb9bb62441deee1f3cbb2ecfec68dc3/Navier-Stokes/nn/DeepONet/learnDeepONet.py#L31-L33

where are the three .npy files located? In the data set link, the NS data set contains the input output pair of shapes (40000, *mesh_size), is this the same file to get the vorticity the variable names suggested above?

Hi @scaomath the data are here https://data.caltech.edu/records/fp3ds-kej20 The input file [NavierStokes_inputs.npy] has 20000 forcing fields The output file [NavierStokes_outputs.npy] has 20000 vorticity fields

May I know how to get these three variables? https://github.com/Zhengyu-Huang/Operator-Learning/blob/b7c484150fb9bb62441deee1f3cbb2ecfec68dc3/Navier-Stokes/nn/DeepONet/learnDeepONet.py#L31-L33

Hi @scaomath , sorry for the confusion here,

You need first download the data

cs = np.load("NavierStokes_inputs.npy")
K = np.load("NavierStokes_outputs.npy")

We do not use theta anymore

Alright thanks.
