Research output: Contribution to journalConference articlepeer-review


A multiwavelet based finite element method (MWFEM) is introduced and applied to the 1D drift-diffusion device simulation. As a result, the MWFEM tracks the unknown function along with its tendency. Hence the spurious oscillation of the conventional FEM is elemented. Numerical example demonstrates that the new method achieves high accuracy and stability for Poisson's equation coupled with the nonlinear drift-diffusion equation with small to large Reynolds numbers.
