A C0 interior penalty discontinuous Galerkin method for fourth‐order total variation flow I: Derivation of the method and numerical results
(2019-02-23)
We consider the numerical solution of a fourth‐order total variation flow problem representing surface relaxation below the roughening temperature. Based on a regularization and scaling of the nonlinear fourth‐order parabolic ...
Direct FEM large scale computation of turbulent multiphase flow in urban water systems and marine energy
Krishnasamy, E.; Hoffman, J.

; Jansson, J. (2016-11-30)
High-Reynolds number turbulent incompressible multiphase flow represents a large class of engineering problems of key relevance to society. Here we describe our work on modeling two such problems: 1. The Consorcio de Aguas ...
FEniCS-HPC: Automated predictive high-performance finite element computing with applications in aerodynamics
Hoffman, J.; Jansson, J.; Jansson, N. (2016-01-01)
; Jansson, J.; Jansson, N. (2016-01-01)
Developing multiphysics finite element methods (FEM) and scalable HPC implementations can be very challenging in terms of software complexity and performance, even more so with the addition of goal-oriented adaptive mesh ...
Adaptive simulation of unsteady flow past the submerged part of a floating wind turbine platform
Jansson, J.; Nava, V.; Sanchez, M.; Aguirre, G.; de Abreu, R.V.; Hoffman, J.; Villate, J.L. (2015-12-31)
; Sanchez, M.; Aguirre, G.; de Abreu, R.V.; Hoffman, J.; Villate, J.L. (2015-12-31)
Offshore floating platforms for wind turbines represent challenging concepts for designers trying to combine an optimal compromise between cost effectiveness and performance. Modelling of the hydrodynamic behaviour of the ...
