ALE and FSI

In this webinar, you receive comprehensive information directly from one of the program developers about the latest developments of the features provided by the solver LS-DYNA to analyse fluids and, in particular, the fluid-structure interaction using its Arbitrary Lagrangean Eulerian (ALE) capabilities.

The theoretical background to fluid modeling in LS-DYNA is presented and illustrated with several practical applications. Problems solved during the workshop include tank sloshing, tank dropping (partially and completely filled), viscous flow in a channel, underwater explosion, bird strike, ship collision and acoustics in air and water.

 

The seminar is directed towards advanced LS-DYNA users, whereas prior knowledge of fluid dynamics is not required.

 

The course will take place from 9-11 a.m. (CET) on three consecutive days.

Please note: The course will be held in Ansys Learning Hub. We will send the credentials shortly before the training.
