A Finite Element Scheme for Shock Capturing Part 7 ppsx

... 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...
