Under the Data Visualization tab, the .gdt and .vap files, corresponding to the saturation levels computed, can be opened, as explained in the FlowDict handbook. No files are available if Discard PDE Solver Files was checked in the Solver settings tab.

For each selected Flow Phase and Computational Direction the solution files for the saturation steps with non-zero permeability are saved and can be loaded by clicking on the Load .gdt and .vap button.

In the structure file (.gdt) you can observe the fluid distribution, while the .vap file contains the velocity and pressure values at each voxel.

Select Structure to load the original structure which is saturated with the displaced fluid. No additional .vap file will be loaded.

Select Structure_z (z can be replaced by x or y, depending on the chosen computational directions) to view the results of the absolute permeability computation.

Shown below is the .gdt file for a 49% invading fluid saturation level. The solid phase (Quartz) is shown together with the Displaced fluid (Air) and the Invading Fluid (Water). The upper part of the image shows the velocity field of the Water with transparent effect on the clipped structure model.

More information about the visualization parameters is available in the Visualization handbook.
