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

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

In the structure file (.gdt) you can observe the fluid distribution, while the .hht (homogenized heat) file contains the concentration values at each voxel.

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

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 concentration field of the Water with transparent effect on the clipped structure model.

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