Computational Euler History

A new pseudospectral calculation of collapsing Euler vortices \cite{HouLi06} has called into question the long-term conclusions of singular behavior described earlier in \cite{Kerr93,Kerr05}. This review is designed to: improve the discussion of the detailed analysis of one test initial condition designed find sources of errors, to compare that with calculations showing no evidence of a singularity, and to document two sets of discussions. Those prior to 1993 between competing teams. And recent discussions of what is needed to reach more convincing conclusions.
