HydraFLASH® Version 3.9.3.0 Officially Released

We are excited to announce the official release of HydraFLASH® version 3.9.3.0, introducing a range of new features and improvements designed to enhance usability, simulation accuracy, and workflow flexibility for engineers and researchers.

This release represents a significant step forward in providing smarter tools for fluid modelling, PVT analysis, and compositional simulation workflows.

Enhanced User Interface

HydraFLASH® now features an improved and more intuitive user interface, making navigation smoother and daily workflows more efficient. The updated design helps users access tools faster while maintaining clarity across complex projects.

Improved Simulation Core

Version 3.9.3.0 includes important enhancements to the simulation engine, delivering improved performance, stability, and reliability when working with complex fluid systems and large datasets.

Editable Component Properties & Binary Interaction Parameters (BIPs)

Users can now directly edit component properties and Binary Interaction Parameters for each fluid composition and Equation of State (EoS). This capability enables:

  • Advanced fluid tuning and calibration
  • Improved matching with laboratory and field data
  • Greater modelling flexibility

Editable tables also include productivity features such as copy-paste support, reset options, and rapid data modification tools.

 

TreeView – Smarter Fluid & Test Management

The new TreeView interface introduces a structured and efficient way to manage fluids and PVT tests:

  • Organized hierarchical navigation
  • Quick duplication, renaming, and editing
  • Copy and reuse tests between fluids
  • Built-in search for fast access

This enhancement significantly improves data organization and workflow efficiency.

Calculation Preferences per Fluid

Each fluid now stores its own calculation configuration, including:

  • Equation of State
  • Alpha functions
  • Mixing rules
  • Viscosity models
  • Interfacial tension methods
  • Gas correction options

This ensures consistent and reproducible simulation results across projects.

Custom Unit System

HydraFLASH® now supports customizable unit systems in addition to standard SI, Metric, and Field units. Engineers can define unit preferences aligned with regional standards or project requirements, with automatic updates applied across the application.

Continuing Our Mission

HydraFLASH® continues to evolve with a focus on precision, flexibility, and usability, empowering engineers with advanced tools to simplify complex simulation challenges.

We welcome feedback from our users and look forward to supporting your workflows with this latest release.
