Fluid Dynamics

A new WAVE-RT tuning solution has been added to R-Desk enabling even faster and more accurate calibration of real-time engine models to steady-state test measurements or donor model results.  To facilitate this, a model convergence detection functionality has been added to WAVE-RT to speed up steady-state simulations.

We continue to focus on emissions calculations and our constant target to make engines more environmentally sound, in this release we have paid particular attention to unburnt hydrocarbons.  Advanced flame quenching controls are now available per boundary allowing users to accurately predict hydrocarbons and their oxidation in the exhaust.  An improved wall-film solver with enhanced convergence criteria and model sub-stepping has been delivered, which improves overall accuracy and solver convergence.  This leads to a speed-up of the wall-film solution of up to 95% over the duration of a typical GDI simulation.

Meanwhile, for thermal analysis of batteries and E-Motors, VECTIS includes a number of improvements that improve usability and significantly speed up CHT solution times.  Additionally, a new boiling model has been added that improves the accuracy for both ICE and E-Motor cooling applications.

Structural Mechanics

2021.2 saw the initial release of Thermal FE in FEARCE delivering thermal solutions for the IC engine.  Based on user feedback, this release delivers usability improvements to this industry-leading solution.

To meet the challenge of reducing oil consumption from the ICE, and building on enhancements made in 2021.2, this release includes enhancements to the oil control ring in RINGPAK to further improve predictions of oil consumption.  RINGPAK results can now also be plotted in R-Post, allowing the user to view and plot cyclic results with ease.

For both ICE and EV vehicles, the increasing power density require reductions in weight and so durability across the sectors becomes more important than ever.  To this end, durability analysis of shafts and modelling of splines are now possible in SABR.  Fatigue results are presented in summary tables allowing very quick assessment of all the shafts and splines of an entire gearbox.  Tooth contact analysis has also been enhanced in SABR-Gear to allow the engineer to assess the risk of scuffing due to micro-pitting.

Enhancements have also been delivered in ENGDYN and FEARCE that reduce solution times and improve productivity.

Systems Engineering

In today's market, manufacturers are faced with shorter times to introduce new vehicle models, increased complexities in powertrain design and fewer available resources. With faster than real-time simulation, IGNITE provides virtual models for all phases of the development process.

This release has several usability improvements to the analysis workflow including the import of FMU models to help meet these simulation demands in less time.
