CONVERGE Studio 5.1.1 is a premier, high-fidelity Computational Fluid Dynamics (CFD) software suite specifically renowned for its revolutionary approach to simulating internal combustion (IC) engines and other systems with complex moving boundaries. Its core innovation is a fully automatic, cut-cell Cartesian meshing technique that generates the grid at runtime, completely eliminating the time-consuming and error-prone manual meshing process for moving parts like pistons and valves. This makes CONVERGE the go-to tool for automotive, aerospace, and power generation engineers conducting detailed analysis of combustion, spray, and turbulence in dynamic geometries.

Core Functional Capabilities of CONVERGE Studio 5.1.1

• Autonomous Meshing for Moving Geometries
  Simulate full engine cycles without manual re-meshing. The software automatically generates a new, high-quality conformal mesh at each time step as pistons and valves move, ensuring robust and accurate simulations even for complex port and chamber designs, including variable valve timing (VVT) and deactivation.

• Advanced Chemistry & Combustion Modeling
  Leverage sophisticated solvers for accurate fuel chemistry. The integrated SAGE detailed chemistry solver allows for the simulation of finite-rate kinetics, predicting key outcomes like ignition timing, combustion phasing, and emissions formation (soot, NOx) for conventional and alternative fuels.

• Comprehensive Spray & Multiphase Models
  Model fuel injection and atomization in extreme detail. CONVERGE includes advanced Lagrangian particle tracking for sprays with models for droplet breakup, collision, evaporation, and wall film formation, which are critical for predicting mixture preparation and combustion efficiency in direct-injection engines.

• Integrated Pre-Processing, Solving & Post-Processing
  Manage the entire simulation in one environment. CONVERGE Studio provides tools for geometry import and preparation, case setup, solver execution, and detailed 3D visualization of results like temperature, species concentration, and flow fields, creating a streamlined workflow from setup to insight.

The CONVERGE Advantage: Predictivity and Efficiency

CONVERGE Studio 5.1.1 has set a new standard in CFD for internal combustion engines by fundamentally changing the workflow. Its autonomous meshing not only saves weeks of pre-processing time but also ensures consistent mesh quality, leading to more reliable and predictive results. This capability, combined with its world-class chemistry and spray models, provides engine developers with an unparalleled virtual test bench to explore new designs, optimize efficiency, and reduce emissions with confidence, drastically reducing reliance on physical prototypes.
