Model Helper Scripts

The generated model files under examples/models/ are intentionally ignored by git. The scripts in that directory are tracked; downloaded archives, extracted SEG-Y files, converted NumPy arrays, and preview figures are local artifacts.

Model preparation steps live with the examples that require those files:

• Marmousi acoustic FWI: 2D Acoustic FWI on Marmousi with Torch
• Marmousi acoustic FWI with JAX: 2D Acoustic FWI on Marmousi with JAX
• Marmousi elastic FWI: 2D Elastic FWI on Marmousi with Torch
• Marmousi acoustic LSRTM: 2D Acoustic LSRTM on Marmousi with Torch
• Marmousi source-encoded acoustic FWI: 2D Acoustic FWI with Source Encoding on Marmousi with Torch
• Overthrust 3D acoustic FWI: 3D Acoustic FWI on Overthrust with Torch
• Overthrust 2D elastic FWI: 2D Elastic FWI on Overthrust with Torch
• Overthrust 3D acoustic LSRTM: 3D Acoustic LSRTM on Overthrust with Torch
