TLDR
The two-dimensional Euler equations have been solved on a triangular grid by a multigrid scheme using the finite volume approach and in its present form, the accuracy and convergence rate of the triangle code are comparable to that of the quadrilateral mesh code of Jameson.
Abstract
The two-dimensional Euler equations have been solved on a triangular grid by a multigrid scheme using the finite volume approach. By careful construction of the dissipative terms, the scheme is designed to be secondorder accurate in space, provided the grid is smooth, except in the vicinity of shocks, where it behaves as firstorder accurate. In its present form, the accuracy and convergence rate of the triangle code are comparable to that of the quadrilateral mesh code of Jameson.
