numerical simulation tsunami
hi
i want to scrutiny effect tsunami on break water,but i dont know which software (ex:flow-3d,ansys-cfx,ansys-flid ...) can best chosed. please help all the best |
For what it's worth, I just saw a presentation on tsunami modelling in FLOW-3D by Osamu Kiyomiya from Waseda University,Tokyo.

hi,
How i can produce tsunami wave in flow3d with piston(wave maker) thanks a lot |
You'll want to use the GMO model to simulate the motion of the sea floor.

hi,
How i can prodouce tsunami wave in flow3d i dont know,how we must use "shallow water" for tsunami wave |
The GMO approach should still work with the shallow water model. Just be sure to keep all of the geometry in the lower cell and it should be fine. Alternatively, you could try using the wave boundary condition to create the waves.

When i use "shallow water",the flow3d want to be number cell mesh in z direction 2cell. my model in z direction have 300cell!
that Seems strange to me what should i do? |
The shallow water model uses depth-averaged equations and therefore only needs two cells in z. It expects all geometry and fluid to be in the lower cell; the upper cell is used to apply the boundary conditions at the free surface. If you define your problem in this way it should work.

How i can place geometry (300 cells in z-direction) into bottom cell?

hi
when i use shallow water and run program. The wave player normally can not be seen. ex:in 2D and X-Z plane, I see the color of the lower cell. can we see shallow water the normal display? |
