How to compare results in GeoDict

The tutorial “How to compare results in GeoDict” introduces different ways to visually and analytically compare structures and simulation results in GeoDict 2022. A cathode structure and its statistical digital twin serve as an example. By synchronizing two GeoDict instances, both structures can be examined side by side while settings such as zoom, slicing, viewing direction, clipping, and 2D/3D visualization are adjusted simultaneously. In addition, structural properties such as the volume fractions of individual materials can be directly compared.

For a quantitative evaluation, PoroDict and the Pore Size Distribution (Porosimetry) analysis are used. The calculated pore size distributions are visualized in the Result Viewer and compared based on characteristic pore diameters. The tutorial also demonstrates how to analyze multiple result files side by side, identify differences in reports and log data, and apply consistent axis settings to plots. Using Combine Results, datasets can finally be displayed in common plots for a clear comparison. Overall, the tutorial provides a practical workflow for GeoDict users who want to investigate similarities and differences between digital structures and their simulation results both visually and quantitatively.

• Visual comparison of structures: Learn how to compare an original structure and its statistical digital twin in two synchronized GeoDict instances.
• Synchronize views: Connect two GeoDict instances for simultaneous visualization.
• Compare in 2D and 3D: Use slicing, clipping, zoom, and rotation to inspect both structures.
• Compare statistics: Analyze material volume fractions and structural differences.
• Calculate pore sizes: Use PoroDict – Porosimetry to determine pore size distributions.
• Visualize pore sizes: Compare pore size fields using consistent color scales.
• Compare results: Open both files in the Result Viewer and compare characteristic values and log data.
