Parametric Darcy Flow

Adjust permeability contrast and correlation length on a unit square with zero-pressure edges and a uniform source to view the input permeability and predicted pressure fields.

Published scope

The inputs, geometry and outputs below follow the registered public case. Published verification applies only to the stated conditions. Service availability requires a live request.

Darcy PINO / FNO

A heterogeneous porous unit square has zero pressure on all edges, a uniform source and a smooth positive permeability field.

Adjust permeability contrast and correlation length to predict pressure on 241 by 241 points alongside the actual input field. Inputs and outputs are dimensionless; this is a numerical-method benchmark.
