Researchers introduce a new neural operator, STONet, to model contaminant transport in micro-cracked porous media efficiently.
STONet architecture includes a DeepONet structure enriched with a transformer-based multi-head attention mechanism, enhancing performance without added computational overhead.
The model integrates different networks to encode properties effectively, predict concentration field changes accurately, and achieves relative errors below 1% compared to FEM simulations.
STONet's computational efficiency allows for rapid assessment of subsurface contamination risks and optimization of environmental remediation strategies.
