How the npy file in tutorial 1 come from?

[jacktang]

Hello there,

I am learning ROM by following the tutorials and I am puzzled with the npy files. I read the coordination info from coord.npy and found it completely disorder. I also searched the discussions and it might come from using Smithers (but I didn't find any example in documentation). And my questions is how to generate the coordination and snapshots npy file? If now I only have coordination csv data and snapshot point data, is it possible to convert to npy file? Thanks a lot!

hi @jacktang, yes you're right, the dataset of the first tutorial comes from Smithers and it is originally created by running finite-element simulations with FEniCS.
But you can use of course CSV files as well, just load them into numpy arrays and you're done!

I do not really get what order are you expecting in the nodes coordinates array, but let us know if you still have doubts!
