ENGYS has released 3.4.0 of HELYX, a general-purpose computational fluid dynamics (CFD) software solution for engineering design and optimization based on ENGYS' open-source simulation engine (HELYX-Core). The new release also includes updates for all of HELYX's add-on solver modules, namely: Adjoint, Coupled, Marine and Hydro.

HELYX 3.4.0 offers a range of extended capabilities and code refinements to remove known issues found in the previous release 3.3.2. Some new features added in this version include:

Mesh

For mesh, there are several features noted: new interactive histogram to display mesh quality metrics in the graphical user interface; improved feature edge snapping for modelling low y+ scenarios with near-wall layers; and improved accuracy and reduced turnaround times for mesh optimization during the layer addition stage.

Setup

For setup, new enhancement include: added support for multi-body rigid motion and thermal solvers for Generalized Internal Boundaries (GIBs); new boundary conditions, including a new synthetic turbulence generator based on the Turbulent Spot Method with Anisotropic Vorton (ATSM) and a new Delaunay triangulation method for time-varying point data at inlets; added support for new ω-equation based transition and SST curvature correction turbulence models; and new, improved thermal comfort outputs based on ISO7243 and ISO7730.

Solver

Find new features such as the following: added support for single-phase, compressible flows in the Unified Solver Framework (USF) via the GUI; improved USF implementation for single-phase, compressible, buoyancy driven flows; and new multi-species, drift-flux solver for modeling settling of solid particles or gas bubbles in liquids.

View

There are several updates: upgraded graphic libraries in the GUI for improved local and remote image rendering; improved GPU-based rendering performed at client side for remote client-server GUI connections; new export of display scenes and view objects to 3D formats such a X3D, PLY and VT.

Helyx

Updates related to HELYX include the following: 

  • HELYX-Adjoint: New enhanced symmetry of adjoint sensitivities around a user-defined plane.
  • HELYX-Adjoint: Improved convergence of adjoint sensitivities for topology optimisation.
  • HELYX-Coupled: New block-coupled adjoint implementation for massive speed up of sensitivity calculations w.r.t. standard adjoint solver segregated approach.
  • HELYX-Marine: New validated calm-water prediction method for both displacement and planning hulls using Adaptive Mesh Refinement (AMR).
