CONVERGE-logo-300x103
CONVERGE is a multipurpose computational fluid dynamics (CFD) code with innovative features including a fully coupled automated mesh created at runtime and Adaptive Mesh Refinement (AMR). CONVERGE:

  • eliminates all user meshing time.
  • automates the setup of moving boundaries
  • eliminates the deforming mesh issues typically associated with moving boundaries
  • creates perfectly orthogonal cells, resulting in improved accuracy and simplified numerics
  • maintains the true geometry, independent of the mesh resolution

Fully coupled with GT-POWER/GT-SUITE:

  • Two-Way Interactive Boundary Coupling
  • Hydromechanical Coupling
  • Exhaust Aftertreatment Coupling

CONVERGE is also fully equipped with a detailed chemistry model and a genetic optimization tool.

  • No User Meshing

    Screw compressor simulation showing cut planes with adaptive mesh refinement

    CONVERGE is a fundamentally different CFD code – it automatically generates the grid at runtime, so you do not need to spend any time creating a mesh.
