Asymptotic-preserving methods for an anisotropic model of electrical potential in a tokamak
Philippe Angot, Thomas Auphan, Olivier Guès
A 2D nonlinear model for the electrical potential in the edge plasma in a tokamak generates a stiff problem due to the low resistivity in the direction parallel to the magnetic fie…
An optimal penalty method for a hyperbolic system modeling the edge plasma transport in a tokamak
Philippe Angot, Thomas Auphan, Olivier Guès
The penalization method is used to take account of obstacles, such as the limiter, in a tokamak. Because of the magnetic confinement of the plasma in a tokamak, the transport occur…
Penalization for non-linear hyperbolic system
Thomas Auphan
This paper proposes a volumetric penalty method to simulate the boundary conditions for a non-linear hyperbolic problem. The boundary conditions are assumed to be maximally strictl…
Orientation dependence of the elastic instability on strained SiGe films
J. -N. Aqua, A. Gouyé, T. Auphan +3
At low strain, SiGe films on Si substrates undergo a continuous nucleationless morphological evolution known as the Asaro-Tiller-Grinfeld instability. We demonstrate experimentally…
