Residual based a posteriori error estimators for eddy current computation
We consider H (curl ;Ω)-elliptic problems that have been discretized by means of Nedelec's edge elements on tetrahedral meshes. Such problems occur in the numerical computation of eddy currents. FromExpand

A new approach for phase transitions in miscible multi-phase flow in porous media
Abstract The tightly coupled, strongly nonlinear nature of non-isothermal multi-phase flow in porous media poses a tough challenge for numerical simulation. This trait is even more pronounced, ifExpand
