Direct FEM computation of turbulent multiphase flow in 3D priting nozzle design
(2020)In this paper, we present a nozzle design of the 3D printing using FEniCS-HPC as mathematical and simulation tool. In recent years 3D printing or Additive Manufacturing (AM) has become a emerging technology and it has ... -
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 ... -
Direct finite element simulation of turbulent flow for marine based renewable energy
Jansson, J.; Nguyen, V.D.; Moragues, M.; Castanon, D.; Saavedra, L.; Krishnasamy, E.; Goude, A.; Hoffman, J. (2017)
In this article we present a computational framework for simulation of turbulent flow in marine based renewable energy applications. In particular, we focus on floating structures and rotating turbines. This work is an ... -
Finite Element Simulations of Two-phase Flow and Floating Bodies Using FEniCS-HPC
Moragues, M.; Castanon, D.; Degirmenci, N.C.; Jansson, J.; Nava, V.; Krishnasamy, E.; Hoffman, J. (2018-07)
We present a variational multiscale stabilized finite element method to solve the variable density incompressible Navier-Stokes equations for the simulation of two-phase flow. We introduce a level-set method based on the ... -
High Performance Scientific Computing in Applications with Direct Finite Element Simulation
(2020-06-18)To predict separated flow including stall of a full aircraft with Computational Fluid Dynamics (CFD) is considered one of the problems of the grand challenges to be solved by 2030, according to NASA [1]. The nonlinear ... -
Simulation of the HarshLab floating platform for offshore experimentation using FEniCS-HPC

Time-resolved Adaptive Direct FEM Simulation of High-lift Aircraft Configurations
Jansson, J.; Krishnasamy, E.; Leoni, M.; Jansson, N.; Hoffman, J. (2017-08-01)
Our simulation methodology is referred to as Direct FEM Simulation (DFS), or General Galerkin (G2) and uses a finite element method (FEM) with piecewise linear approximation in space and time, and with numerical stabilization ... -
Towards HPC-Embedded Case Study: Kalray and Message-Passing on NoC
(2017)Today one of the most important challenges in HPC is the development of computers with a low power consumption. In this context, recently, new embedded many-core systems have emerged. One of them is Kalray. Unlike other ...
