Hi everyone, mi name is Miguel an student of Civil engineering in Universidad de Sevilla (Spain). I'm doing a numerical simulation of the great Lisbon tsunami using Gerris. My problem is that the tsunami wave does not spread to the american east coast (and should), i have four suspects:
- The dissipative forces are very strong - Meshing criterion - The minimum cell size is not small enough - The way of calculate the advection terms (The flux limiter that I'm using is sweby gradient) This is the code that i use for the bottom friction. FRICC = 1e-3 U = P > DRY ? U/(1. + dt*Velocity*FRICC/P) : 0 V = P > DRY ? V/(1. + dt*Velocity*FRICC/P) : 0 Can anyone suggest me something? If anyone want complete the code, ask me please. Cheers |
