Abstract (summary):
Research and development of high-order methods in the past decade have focused on obtaining more accurate solutions with the additional advantage of decreasing overall computational cost and memory requirements. The present research focuses on implementation of the CENO reconstruction scheme for three-dimensional unstructured meshes. The CENO reconstruction scheme makes use of a hybrid reconstruction technique based on a fixed single central stencil which is particularly advantageous for unstructured meshes. A smoothness indicator facilitates the switching from a k-exact reconstruction in smooth regions of the solution to a limited piecewise linear reconstruction in unresolved or discontinuous regions. This scheme has been implemented to reconstruct both continuous and discontinuous functions on three-dimensional unstructured tetrahedral meshes.
