A Nodal Approach to Arbitrary Geometries, and Adaptive Mesh Refinement for the Nodal Method

258 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2002.The third limitation associated with the nodal method is removed by modifying an existing implementation of the NIM to incorporate fast and accurate preconditioner and solver routines. Application of this modified implementation to convection-diffusion problems proves that the coarse mesh efficiency of the nodal method can be maintained by taking advantage of "off the shelf" advanced solver technology.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
