However, he repeatedly would get into situations where area under curve for one of the lineouts was off by 5x to 10x.\r\n\r\nWe exported the 3 lineouts to ultra. Low and behold, ultra said there were 4 curves, not three. One of the curves from VisIt was broken into two curves. There was a discontinuity in it when it was exported to ultra. However, as displayed in VisIt's viewer, no such discontinuity existed. The break appeared near a point where there may have been an artificial spike (see another ticket from Brad about spurious spikes in linout). When ultra did the integrals, the sum of the first two curve pieces was the value we'd expect.\r\n\r\nWhen we exported the 3 lineouts to vtk, we got a .visit file with !NBLOCKS 3 and referred to the 3 .vtk files. When we re-read those VTK files back into VisIt (not curves now but 1d meshes), they plot fine but now also show the break (e.g. discontinuity) in one of the curves. And, when we compute area under each curve, we get correct numbers.\r\n\r\nSo, somewhere under the curves during the process of taking a lineout, a curve was discontinuous somehow. That discontinuity did not show up in the plotted curve but did show up when integrating. The integration query only considered one portion of the curves.\r\n\r\nHank says this behavior is new. He hasn't seen same in previous versions of VisIt and his been doing this kind of thing for months.\n\n\n\n-----------------------REDMINE MIGRATION-----------------------\nThis ticket was migrated from Redmine.
