Autodesk Simulation - Multiphysics

( Duration: 2 Days )

The Autodesk Simulation - Multiphysics training course will introduce you to performing computational fluid dynamics (CFD) analyses on 3-D models. All of the available load and constraint options for CFD analyses will be covered. You will learn how to evaluate the results of CFD analyses and create presentations of the results, including images, animations, and HTML reports.
