Simulations of incompressible flows are performed on a daily basis to solve problems of practical and industrial interest in several fields of engineering, including automotive, aeronautical, mechanical ...
Miranda Neiva, Eric (Fecha de defensa: 2020-10-07)
This thesis addresses large-scale numerical simulations of partial differential equations posed on evolving geometries. Our target application is the simulation of metal additive manufacturing (or 3D ...
Barbat Vlad, Gabriel (Fecha de defensa: 2021-02-11)
The numerical modelling of fracture has been an active topic of research for over five decades. Most of the approaches employed rely on the use of the Finite Element Method, which has shown to be an ...
Reyes Sotomayor, Ricardo (Fecha de defensa: 2020-03-23)
This thesis presents the a stabilized projection-based Reduced Order Model (ROM) formulation in low speed fluid flows using a Variational Multi-Scale (VMS) approach. To develop this formulation we use ...
Moreira Filho, Carlos Augusto (Fecha de defensa: 2022-07-21)
This thesis develops numerical methods to improve the accuracy and computational efficiency of the part-scale simulation of Additive Manufacturing (AM) (or 3D printing) metal processes. AM is characterized ...
