Data Visualization

In the Data Visualization tab, you can load the *.pas files for the intrusion and, if selected, the extrusion, and the step-by-step images of the computed process.

Visualization of Pressure and Saturation (pas file)

Click Load to access the pressure and saturation field data saved in the PressureSaturation.pas file.

Depending on the choice made under the output options the Pore Filling Pressure and the Pore Filling Saturation (Invading) can be selected for the visualization. Click OK to load the selected fields.

SatuDict_MICP_DataVisualization_LoadPAS

The initial visualization, in 2D view or 3D rendering, is done using default settings which you can modify (see the Data Visualization in Capillary Pressure Curve for an example). These parameters can be found under the Volume Field tab in the Visualization Panel, above the Visualization Area. For more information on a particular visualization setting, see the Visualization chapter.

Visualization of intermediate states (gdt files)

Finally, the computed process can be visualized step-by-step with GDT files saved during the MICP calculation. This is only possible if Write All .gdt or Write Only Changed .gdt was selected in the Output Options section. The GDT files corresponding to the computational steps (Injection_000000.gdt, Extrusion_000000.gdt etc.) are stored in the automatically created result folder.

To analyze these images, make sure that the visualization of the Structure is switched on (View Structure, in the menu bar).

SatuDict_MICP_DataVisualization_LoadGDT

Select one of the GDT files, where the file names correspond to the simulation step in which the GDT file was saved. Also, the pressure and saturation of the invading fluid in this step are shown to easier identify a specific step.

Click Load gdt to open the desired file which is displayed in the visualization area.
