Tsunami simulation lifecycle in FUNWAVE

[Soroush Kouhi]

Hello all, 

We are using FUNWAVE to model the full lifecycle of a tsunami for emergency preparedness. Given the solver's inherent numerical dissipation, is there a recognized 'rule of thumb' for the temporal validity of results for near- and far-field tsunmis? Is there a theoretical or empirical basis for a 'cutoff time' after which the results unreliable? 

Conversely, if the first few hours of a simulation produce promising results, can we reasonably assume that the remainder of the simulated tsunami lifecycle will also be reliable?

Appreciate your feedback. 

Kind Regards, 

Soroush
