SOLPS-NN Training Data v1
This repository contains the condensed SOLPS-ITER simulation data used to train surrogate models as part of the PhD Thesis “Surrogate models for particle and power exhaust in divertor tokamak simulations” of S. Dasbach conducted at the Forschungszentrum Jülich.
| File/Folder | Explanation |
|---|---|
| baserun | Contains the SOLPS-ITER baserun used to conduct the parameter scan |
| geometry | The files crx.npy / cry.npy contain the x and y coordinates of the 4 corners of each grid cell in the computational grid. |
| train | Data used for training of surrogate models (Sobol sequence distribution) |
| test | Data used for testing of surrogate models (Random distribution) |
| example.py | Example python script to plot the data |
| thesis.pdf | Copy of PhD thesis documenting the data generation process |
Description of train/test data
| File | Explanation |
|---|---|
| simulations.db | SQlite database containing the parameters of all attempted simulations even if these crashed |
| completed | sim_ids of all simulations that achieved a result |
| failed | simd_ids of all simulations that crashed |
For all simulations which completed the following data is provided:
