[Dune] publications about Dune parallel scalability and performance

[Ziad Boutanios]

Hi Christoph,

I have an extensive background in multiphase flows using both FEM and 
FVM. My interest in DG for incompressible multiphase simulations stems 
from the suitability of the method for hyperbolic problems. It is also 
quite good for volume fraction transport equations where the volume 
fraction needs to be bounded between 0 and 1.

I recently wrote a CG/DG code for a Eulerian-Eulerian formulation using 
UFL with good results but it is very slow compared to FVM. Such a code 
can be used for aero-icing, sediment transport, drifting snow, 
particulate flow through porous media, etc. Right now I am looking to 
modify the equations and make the code faster, maybe use DG for all 
equations if it helps parallel runs.

My interest in Dune is due to improved mesh handling and availability of 
automatic mesh adaptation. This is a research project I'm doing 
part-time for lack of funding but I am open to collaborations if someone 
has a common interest and could get involved full-time.

Kind regards,

Ziad
