Major New Features in ISATIS.NEO 2025.3

The 2025.3 update introduces several powerful features that enhance modeling accuracy, workflow flexibility, and visualization capabilities.

---

Soft Boundaries for Improved Geological Modeling

One of the most important additions in ISATIS.NEO 2025.3 is the Soft Boundaries utility.

Traditional geostatistical modeling often relies on strict domain boundaries where samples outside a domain are ignored. However, geological formations frequently transition gradually rather than abruptly.

The Soft Boundaries tool allows users to:

• Expand mesh selections by a configurable distance
• Include neighboring samples across geological boundaries
• Improve interpolation accuracy in transitional zones
• Reduce artificial discontinuities between domains
• Better reflect real geological conditions

This capability significantly improves grade estimation accuracy in complex deposits, particularly where geological units interact or overlap.

---

Multivariable Capping in Estimation Workflows

ISATIS.NEO 2025.3 introduces a new multi-variable capping system within neighborhood estimation settings.

In many geological datasets, extreme values must be capped to prevent bias in resource estimation. The new functionality allows users to:

• Apply capping thresholds to multiple variables simultaneously
• Define separate low and high limits per variable
• Configure no-capping distances for spatial control
• Maintain consistent estimation parameters across multiple datasets

This improvement simplifies resource estimation workflows while maintaining rigorous control over extreme sample values.

---

Advanced Local Anisotropies Modeling

The Local Anisotropies module has been significantly enhanced in this release.

Geological formations often have directional continuity patterns that vary across space. Accurate modeling of anisotropy is critical for reliable interpolation and simulation.

Enhancements include:

• New algorithms for sub-horizontal reference surfaces
• Smoother transitions between anisotropy orientations
• Improved numerical stability
• Faster computational performance
• Better representation of structural geological trends

These improvements allow users to create more realistic spatial models that reflect natural geological structures.

Expanded Simulation Capabilities

ISATIS.NEO 2025.3 introduces a new Simple Kriging conditioning option for PluriGaussian simulations.

Simulation workflows benefit from:

• Increased flexibility in stochastic modeling
• Improved statistical rigor for stationary datasets
• Enhanced uncertainty modeling capabilities
• More accurate probabilistic geological simulations

These features are particularly valuable for risk assessment, scenario modeling, and uncertainty quantification.

Enhanced 3D Visualization and Model Interpretation

Visualization plays a critical role in interpreting spatial data and geological models. ISATIS.NEO 2025.3 introduces several improvements to the visualization system.

Display Values Directly in 3D Grid Cells

Users can now display variable values directly inside grid cells within the 3D Viewer and Section Viewer.

New visualization capabilities include:

• Cell value labels within block models
• Customizable fonts and colors
• Background color highlighting
• Adjustable cell spacing and exaggeration
• Improved section view readability

These features allow geoscientists to quickly understand spatial patterns and validate model results visually.

---

Improved Python Integration and Automation

ISATIS.NEO includes powerful automation features through Python scripting, and the 2025.3 release expands these capabilities.

New improvements include:

• Integrated Python environment management
• Ability to install external Python libraries directly inside projects
• Improved scripting automation for modeling workflows
• Better integration with data science and machine learning tools

Python support allows users to automate repetitive tasks, create custom workflows, and integrate ISATIS.NEO with broader data science pipelines.
