摘  要:In this presentation we will first introduce the immersed finite elements to efficiently solve elliptic interface PDEs on structured meshes. Then two applications to the problems of charging in space will be discussed: the ion thruster and the electrostatic levitation of lunar dust. The later one is one of the greatest inhibitors to a nominal operation on the moon. Finally, the immersed finite elements will be extended to a moving interface PDE for more applications.
