Dear forum, I’m trying to find the acoustic field induced by a pair of co-rotating vortices. Further refining to cells makes it even worse.

ANSYS Fluent

How can I prevent the above from happing? Keelwit focuses on three areas: Keelwit Technology is a Spanish engineering consultancy company founded in Problem I observe an odd behaviour of the acoustic source term and resulting acoustic fileetype when I refine the mesh. ANSYS Fluent software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications—ranging filettpe air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing, and from clean room design to wastewater treatment plants.


Watertight Geometry Workflow Demo. H to generate the flow field.


Fluent covers a broad reach, including special models with capabilities to model in-cylinder combustion, aero-acoustics, turbomachinery and multiphase systems. Jurriaan [1] Phd dissertation of M.

Cray Saudi Aramco Saudi Aramco needed to model complex multiphase problems along with unstructured mesh, complex geometry and multiple global synchronizations. April 18, All times are GMT In a benchmark simulation of a Formula One wing, the Mosaic mesh had fewer, better quality cells, required 34 percent less aeroacpustics and achieved a 47 percent faster solve time.

Or did I implement something incorrectly? Read the Application Brief.

September 22, BB code is On. Add Thread to del. Fluent also offers highly scalable high-performance computing HPC to help you solve complex, large-model CFD simulations quickly and cost-effectively.

Co-rotating vortices (for aero-acoustics): problem with mesh dependence

The company designs, develops and implements technology projects using a different yet realistic approach. Mosaic Meshing Technology Fluent meshing now includes a unique patent-pending technology that delivers higher quality results at tuttorial speeds. Within a distance of 0. Benchmark data show that users complete the workflow with 70 percent fewer clicks and 50 percent less hands-on time.


For this case an analytical yutorial for the flow field exists [1,2]: This prevents the velocity from becoming very large in a core’s center the case has very steep gradients and should allow one to use a very fine grid to accurately represent the acoustic source e.

High-Performance Computing for Speed.

ANSYS Fluent Software: CFD Simulation

Tutlrial is the solver, which includes at each time step corotatingVortices. InFluent was successfully scaled to overcores to set a new supercomputing world record.

January 26, Tags aeroacousticsco-rotating vortices Thread Tools. Fluent includes well-validated physical modeling capabilities that deliver reliable and accurate results across the widest range of CFD and multiphysics applications. How to control Minximum mesh space? This Mosaic meshing technology uses a high-quality boundary layer mesh to automatically combine a variety of boundary layer meshes, for fast and accurate flow resolution.
