Acceleration of Linear-Implicit Time Integration Schemes Using Subspace Projection Techniques for Electro-Quasistatic Field Simulations

Adaptive linear-implicit time integration applied to the simulation of electro-quasistatic fields in the time domain is presented. The resulting linear systems of equations in one specific time step can be treated as a multiple right-hand side problem, where the solution process of the linear systems of equations is accelerated using subspace projection techniques. First numerical results for a technical application are presented
