TitlePostdoc in computational plasma (solar atmosphere modelling)
CategoryPostDoc Position
EmployerKU Leuven (Center for mathematical Plasma Astrophysics)
InternationalYes, international applications are welcome
Closure DateFriday, January 31, 2020
The Center for mathematical Plasma Astrophysics (CmPA) at KU Leuven and 
the COOLFluiD team are looking for a qualified individual for continuing 
the development of a data-driven novel solar coronal models under a project funded by the US Air Force. The models to be developed start from a fast 
steady-state single-fluid MHD model, which will be made time accurate as 
a first step and then extended to two-fluid (ions, electrons) and three-fluid (ions, electrons, neutrals), so that the chromospheric physics can be taken 
into account as well.
All models will be implemented within the massively parallel Finite Volume
plasma solver in COOLFluiD, ( 
an open-source platform for multi-physics simulations entirely written in C++.
The COOLFluiD plasma solver already features single-MHD and two-fluid models 
for both 2D and 3D simulations, is fully implicit and also includes novel mesh
r-adaptive algorithms that rely on the solution of a pseudo-elastic system to move the grid according to plasma/flow field features. The parallelization is based on MPI but some models are also GPU-enabled (CUDA-based).

The targeted time-accurate MHD model, which relies on a fast Poisson solver 
for the Potential Field Solar Surface (PFSS) to determine the initial magnetic field,  will enable self-consistent data-driven MHD modelling of solar eruptions, starting from real magnetogram data as a photospheric boundary 
condition for the PFSS and will be coupled to EUHFORIA, our heliospheric 
wind and flux-rope CME evolution model. 

The subsequent extension to a multi-fluid formulation (two- and three-fluids), will enable to include the lower layers in the solar atmosphere and thus 
the effect of partial ionization (self-consistently and not just considering additional heating due to ambipolar diffusion), thermodynamic non-equilibrium and non-LTE radiation. 

The ideal candidate, who will join the interdisciplinary COOLFluiD team currently including 10 young/senior researchers (between CmPA and the 
Von Karman Institute), within one of the strongest departments in 
astrophysical plasma modeling in Europe (2 ERC grants at the moment), 
must have the following expertise:

•a background in computational modeling of magnetized plasmas;
•solid programming skills with, in particular, experience with Python and C/C++;
•familiarity with pre- and post-processing tools such as Gmsh for mesh generation and Paraview or Tecplot for visualization is highly desirable;
•experience with Finite Volume algorithms and/or parallel computing (MPI 
and/or CUDA) are considered additional assets.

The position in question is for 2 years (possibly extendable) and includes travel budget to attend international conferences and an annual US Air Force review meeting in US. The position will be closed as soon as we find a 
suitable candidate, even before the closure date. 

An official link to the position on the university website will be posted 
soon. In the meantime interested candidates can already mail to with cc to
