Calibration of a Numerical Simulation with Experimental Results Critical for Reliable Predictions

Every numerical method relies on the accurate choice of models, solver settings, and material parameters in order to be able to mimic real-world behavior. This also applies to Discrete Elements Method (DEM) simulations. You could use standard material properties, but adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations.

You could use standard material properties, but if you want to simulate reality, it is important to understand that the materials actually vary from site to site. Adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations. Even with basic materials, friction and restitution coefficients between particles and particles and boundaries have to be adjusted in order to accurately predict the bulk flow behavior. When extra forces come into play, such as adhesion forces, those additional parameters also need to be selected and properly specified. Continue reading

ANSYS Webinars, Seminars and Events This Week – Oct. 8

Ask the Expert – Benefiting from Cyclic Symmetry in ANSYS Mechanical and Mechanical APDL 14.0

Wednesday, October 10, 2012
4:00 pm EDT, 8:00 pm GMT (REGISTER)

A geometry is called cyclic symmetrical when a structure is rotationally symmetrical about one axis so that the full structure can be produced by copying the cyclic portion. Fan wheels, spur gears, and turbine blades are all examples of structures that exhibit cyclic symmetry. For example, a 36-blade turbine wheel assembly may have 36 repeating 10 degree segments. ANSYS Mechanical and Mechanical APDL can use cyclic symmetry to more efficiently solve static, modal, harmonic, and buckling analysis. It is only necessary to build and mesh one of the repeating segments, so the efficiency gain can be significant. Mechanical and MAPDL will solve for the behavior of that sector and use that single-sector response to construct the response for the full component. This ANSYS webinar will explain how cyclic symmetry models are created and analyzed using ANSYS Mechanical and Mechanical APDL 14.0.

ANSYS Webinars and Events This Week – July 30

image of Learning text on a keyboardThis week we have two ANSYS webinars, one of which is a continuation of our Ask the Expert Series.

Kicking off today is the 20th International Conference on Nuclear Engineering & ASME Power Conference in Anaheim, California. The focus of ICONE is on the technical state-of-the-art and the current status of nuclear power around the world.  ANSYS experts will be on hand in Booth #410 to answer your questions, so please stop by and say hello.

On Thursday, Aug. 2nd, in Portland, Maine, join us for a full-day seminar providing an in-depth technical overview of ANSYS design and analysis software for marine applications. This event is free.

Our Ask the Expert series hosts Part 1 of a 3-part series covering multiphase models in ANSYS CFD. Register today!
