The Tau3P time-domain computational electromagnetics code is used at the
Stanford Linear Accelerator Center for a wide variety of accelerator design tasks. The code
uses the Discrete Surface Integral method to solve Maxwell's equations on primal and dual
hexahedral meshes. In this method run times are highly sensitive to mesh quality,
particularly to minimum edge-length, element skew, and lack of smoothness. In this study
we investigate methods for increasing Tau3P run times via mesh quality optimization. It is found
that abort-time can be significantly increased via optimization of the mesh condition number or
by Laplacian smoothing.
