FlowDict solves a boundary value problem consisting of

• domain boundary conditions that set up the experimental conditions,
• an equation of motion that describes stationary fluid flow in the pores, and
• boundary conditions at the pore walls.

The solution of this boundary value problem is then analyzed and post-processed. FlowDict derives material properties and averaged flow characteristics from the computed 3D result fields.

To solve the partial differential equations, three different flow solvers are available: EJ, SimpleFFT, and LIR. Each of the solvers uses a different numerical approach and thus has different advantages.
