BENCHMARKING LAVA FLOWS -BM1- DAM BREAK FLOW

Abstract
The lava flow team has agreed on benchmarking series.
Among which, benchmark #1 represents a dam break benchmark test.
Flow Characteristics:
The reservoir box is defined by its height (H) and length (L). The width of the box equals the length (W=L). The aspect ratio (L/H) of the reservoir is defined with the standard of 6.6 and 1.3; the recommendation is to start with the 6.6 one. The runout of the box must be at least 10L.
Here we test Newtonian rheology of a perfect fluid. Note however that non-Newtonian solutions of plastic fluids also exist for later consideration.
We recommend the following parameters for codes needing dimensions:
L = 6.6;
H = 1;
Runout Distance = 66;
Total Box length = 72.6;
Density = 2700;
Viscosity = 1E4;
Simulation Time = 1.65E6;
We provide a DEM under the files 'X.txt', 'Y.txt' and 'Z.txt'.
