Abstract
User-Programmable Features (UPFs) are ANSYS capabilities for which users can write their own routines. As such, UPFs make it possible for users to tailor the Mechanical APDL program to their needs. For example, defining a new material behavior, implementing a new finite element, or defining a new contact interfacial behavior are tasks that can be achieved via UPFs. Emphasis will be given to USERMAT, a dedicated routine that allows users to implement their own material model.
Fluid-Structure Interaction (FSI) occurs when a fluid flow interacts with a solid structure / bodies. Flow may exert pressure and / or thermal loads and these may cause (i) structural deformations significant enough to change the fluid flow itself (2-way FSI) or (ii) the deformations may be neglected on the fluid side (1-way FSI). An example which considers the large deformation of a hyperelastic flap as a result of the hydrodynamic forces from a surrounding fluid flow will be discussed.
Short bio
Davide Fugazza received his Laurea degree (July 2000) cum laude in civil engineering from the University of Pavia, Italy, and his international MSc and PhD degrees (in June 2003 and December 2005 respectively) in earthquake engineering from the European School for Advanced Studies in Reduction of Seismic Risk at the University of Pavia as well. Between 2004 and 2005 he spent approximately one year as a visiting research engineer at the Georgia Institute of Technology (Atlanta, USA) and in June 2005 he was recipient of the Young Researcher Fellowship Award in computational mechanics awarded by the Massachusetts Institute of Technology (Cambridge, USA). After graduation he has earned a nine years’ experience as an application engineer in the field of numerical simulations, with an extensive use of finite element packages for consulting activities, research projects and training classes. Since June 2011 he has been working for ANSYS Belgium as a customer and sales support engineer for mechanical-related applications.
