Under the Constituent Materials tab, the Invading Fluid and Displaced Fluid can be entered. The tab is similar to the one for Capillary Pressure Curve but some properties cannot be entered (e.g. surface tension and contact angle).

If the phase distribution under the Wetting Parameters tab is chosen by Pore Size, the displaced fluid must be present in the structure and can be chosen from the drop-down menu. If the phase distribution is taken from Simulated Wetting Process, then both fluids are defined by the capillary pressure curve result file.

In the Permeability panel define the permeability for porous materials in the structure.
