My name is Johan Jansson, I'm Assistant Professor at KTH in the Computational Technology Laboratory (CTL) at the Computational Science and Technology Department (CST), and leading the CFD Computational Technology research line at the Basque Center for Applied Mathematics (BCAM).

We have the aim of developing automated and adaptive finite element methods and the open source FEniCS-HPC software framework for solving partial differential equations based on FEM with good scaling on massively parallel computers. A particular focus in the Unicorn component of FEniCS is on turbulent flow and fluid-structure interaction, and I also develop applications in aerodynamics and biomechanics.

recent highlights

BCAM summer school

Summer School on Advanced Computation in Fluid Mechanics - "New Theory of Flight", June 29-July 1, 2016

BCAM - Basque Center for Applied Mathematics, Mazarredo 14, Bilbao, Basque Country, Spain

The course material, including the FEniCS-HPC open source software for reproducing results in our research, is available on the course page

new theory of flight

Based on our computational mathematical methodology we have developed a new theory of flight published in the Journal of Mathematical Fluid Mechanics which enables understanding of the mechanics of flight, updating the old 2D lift theory to 3D and validated by FEniCS simulation. The article is also available on ResearchGate

simulation of full aircraft

Simulation of aerodynamic forces on a full aircraft as part of the HiLiftPW-2 NASA/Boeing-organized workshop:

Lift coefficient, cl, and drag coefficient, cd, vs. angle of attack, α, for the different meshes from the iterative adaptive method for the full aircraft. As a comparison we also plot results submitted by several other groups to the workshop:

vocal folds

Recent results from the Unified Continuum model with fluid-structure data and implicit contact modeling, here applied to simulation of the vocal folds as part of the EUNISON FP7 project:
