An efficient, scalable numerical algorithm for the simulation of electrochemical systems on irregular domains

摘要: We present a projection method for the solution of diffusive transport and reaction equations electrochemical systems on irregular time-dependent domains. Specific applications include electrodeposition copper in sub-micron trenches, as well any other system with an arbitrarily shaped bulk region dilute electrolyte solution. Our uses finite volume spatial discretization that is second-order accurate throughout, including nonuniform used transition to far-field chemical concentrations. Time integration performed splitting technique includes step solve electric potential. The resulting first-order time, observed be stable relatively large time steps. Furthermore, algorithm complexity scales very respectably grid refinement naturally parallelizable.
