Fluids Product Highlights

With ANSYS 18.1, every engineer can create better, more accurate computational fluid dynamics (CFD) simulations. 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 enable engineers to solve CFD problems with more accuracy than ever before. Breakthrough harmonic analysis delivers accurate turbomachinery simulations up to 100x faster. ANSYS 18.1 also introduces CFD Enterprise, the first solution designed for CFD experts in organizations who need to solve the toughest problems.

Get accurate, reliable turbomachinery simulation results 100X faster with harmonic analysis

Turbomachinery blades must be optimized to achieve superior performance. Previously, the flow for every blade in every row had to be painstakingly calculated — a prohibitively expensive undertaking. ANSYS 18 introduces harmonic analysis to solve these problems in the frequency domain, dramatically accelerating the solution by up to 100x while significantly reducing the hardware requirements, enabling you to obtain a full-wheel solution by calculating as few as one blade per row. Harmonic analysis is not an approximation — the results match the full wheel solution.

You can now apply complex vibrational modes from a cyclic modal analysis to CFX flutter analysis. This reduces the problem size and time to convergence for simulations of radial turbomachinery, such as centrifugal compressors and turbines found in turbochargers, which have blades connected by a relatively thin hub at the outer radius. The new capability captures hub section movement in addition to that of the blades. These problems can be solved using Fourier transform or harmonic analysis, significantly reducing the overall size of the problem and time to convergence.

ANSYS AIM provides easy prep and meshing for ANSYS Fluent simulations

Now you can take advantage of ANSYS AIM’s fast, intuitive workflow to prepare and mesh geometry for solving in ANSYS Fluent. That enables you to include more advanced fluid physics in the simulation and facilitates collaboration with simulation analysts who can validate results. Reliable data transfer between simulation tools used by design engineers and simulation analysts is required to streamline the product development process.

ANSYS Forte delivers faster, higher-fidelity diesel engine simulations

With enhancements to ANSYS Forte, you will be able to simulate diesel engines faster and with more accuracy. Greater flexibility to set up in-cylinder simulations using periodic boundaries speeds solution time by up to 9X for a 9-hole injector while providing high-fidelity results. New turbulence models for large eddy simulation improve prediction of flame lift-off and ignition delay, especially for conditions where local mixing dominates such behavior. Full-cycle diesel simulations including enhancements have been validated in recent technical papers published by SAE.

ANSYS Forte

Overset mesh capabilities decrease the simulation time of pressure contours encountered during rocket booster separation by reducing the number of mesh cells by 70 percent.
