Fluid Dynamics – ANSYS 18 Innovations

ANSYS Release 18 is packed with lot of innovative features for computational fluid dynamics. This article summarizes the various advancements in the new release.

As always, ANSYS has delivered continuous product advancements. The latest release features several beneficial capabilities.

With ANSYS 18, engineers can create better, more accurate computational fluid dynamics (CFD) simulations. Therefore, engineers new to CFD will benefit from greatly expanded capabilities in easy-to-use ANSYS AIM, including support for transient flows, non-Newtonian fluid viscosity and fluid momentum. In addition, ANSYS 18 includes new features and functionality that enables engineers to solve CFD problems with more accuracy than ever before. Further breakthrough harmonic analysis delivers accurate turbomachinery simulations up to 100x faster. ANSYS 18 also introduces CFD Enterprise, the first solution designed for CFD experts in organizations who need to solve the toughest problems.

Here are the release highlights.

GUI & Advances in Post-Processing

The new release has better CAD import, enriched post-processing, well-organized realization of different volumetric domains and surface boundaries. Also the sophisticated solution monitoring and elegant post processing views make up for a delightful user experience with ANSYS 18.

Better Physical Models
  • Heat Transfer and Combustion. Monte-Carlo radiation model helps capture high temperature radiation in solid domains with better ray tracing implementation. Further on, enhanced flamelet modeling gets combustion analysis running better with ANSYS 18.
  • Multiphase Flow Models. Chemical mixing and other fluid blending processes benefit by the convergence and significant speedup improvements for free surface transient flow simulations with the Volume-of-Fluid (VOF) method.
  • Turbomachinery Enhancements. You can solve blade flutter cases more efficiently by using harmonic analysis. In addition, flank-milled blades can now be better modeled with ANSYS BladeModeler.
Solver Enhancements

Lastly with solver enhancements, mesh adaption of polyhedral meshes in ANSYS Fluent is now possible with its improved execution. Another aspect is that of overset meshing which is ready to better support the aerodynamic community.
