my myopic view is tainted because my applications are nearly hyperbolic and everything of interest is downstream of a shockwave. so even for flows over blunt bodies where the shock layer is smooth, at some point upstream pollution becomes dominant. it is of course theoretically possible to use a low order element and allow h-adaptivity to resolve the shock, but you need ridiculously small elements to mask the pollution. of course, I'd love a demonstrated counter example... -Ben ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Libmesh-devel mailing list Libmesh-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-devel
