Cremonesi et al benchmark
Revision as of 01:16, 29 March 2011
This benchmark for simulations of landslide tsunamis generated by a deformable slide using Gerris is based on these articles:
Zweifel, A., Zuccala, D., Gatti, D. - Comparison between computed and experimentally generated impulse waves
- Journal of Hydraulic Engineering 133(2):208--216, 2007
Cremonesi, M., Frangi, A., Perego, U. - A Lagrangian finite element approach for the simulation of water-waves induced by landslides
- Computers and Structures In press, 2011
Here the slide is modeled as a Bingham fluid. The setup is well described in (Cremonesi et al., 2011) except for the initial position of the slide that I could not find in the papers. Fortunately, I managed to digitize the initial position of the slide from Figure 10-1 and 11-1 of (Cremonesi et al., 2011).
Two configurations are tested here. First the case of a slide with no initial velocity (initial x coordinate of the leading edge of the slide = -0.5 m with respect to the shoreline), and then that of a slide with an initial velocity of 3.153 m/s (initial x coordinate of the leading edge of the slide = 0.84 m with respect to the shoreline).
