The functionalities of the ‘3DHIP-Calculator’ software
3DHIP-Calculator is shown with an intuitive graphical user interface that help their utilization. The results are presented in different graphs (histograms and cumulative probability functions) and 2D maps. The output data can then be exported to Geographic Information Systems for more detailed 2D mapping to show probabilities of the available resource (for example, 10% HIP (P10)), HIP (P50) or HIP (P90).

Application distribution
3DHIP-Calculator is distributed in a compiled executable program for Microsoft Windows™ (3DHIP-Calculator.exe).
The current version of 3DHIP-Calculator 1.2 (August 2022), can be downloaded using a zip compressed file (3DHIPCalculator_v1.2, 21 MB) containing:
- The 3DHIP_Calculator.exe software.
- The English version user guide (PDF).
- Test examples to the application:
- 3D geological and thermal models voxel format (geological_model.vox, thermal_model.vox, from Herms et al., 2020). See section 4, user guide.
- 1D geological model (1D_geological_model.txt). Example case of an idealized conceptual theoretical model using a single cell. See section 6, user guide.
