A Finite Element Scheme for Shock Capturing Part 4 docx

... variation for each element and flags those elements which have a high variation as needing a larger value of a for shock capturing. Note that this would work even in a Galerkin scheme since ... the comparison is to actual flume data. The comparisons are made to the water surface heights and timing of the shock passage. The final case is a steady-state comparison t...

... go to smaller grid spacing. Values of C, less than 1 appear to lag the analytic shock and Cs greater than 1 leads the analytic shock. With the largest C, the calculated shock speed ... depth and Ah is the analytic depth difference across the shock, 0.1 m. The error was as small as was detectable by the technique for measurement of speed at AX = 0 .4 m so ther...
