A mixed-dimensional model for direct current simulations in presence of a thin high-resistivity liner
Alessio Fumagalli, Lorenzo Panzeri, Luca Formaggia +2
In this work we present a mixed-dimensional mathematical model to obtain the electric potential and current density in direct current simulations when a thin liner is included in t…
