The capillary bundle structure can be built using any of the three viewers for PoreXpert, the 3D cell inspector, 2D cell inspector or the external full screen 3D viewer. The next screen shows the completed building screen after fitting a capillary bundle. The building screen for the capillary bundle model does not display the simulated curve as it matches the experimental curve.

 

 

The 3D cell inspector representation of the outcrop sandstone shown as capillary bundles is shown in the next figure, but you have to consider whether this a more representative structure than the void network model shown in the initialisation building tutorial.

Capillary bundle representation of the outcrop sandstone shown using the 2D cell inspector. In the left hand xy-plane image you can see the capillary sizes looking from above, the right hand side xz-plane represents the cell from the back of the cell moving towards the front of the cell.
