Hi,

I am modelling a surge in T3D. With 3 vertical layers I get a realistic surge (approx equal to the water level change from the inverse barometer equation). However, when I add more layer e.g. 10, the surge height becomes greater. Does anyone know the explanation behind this?

Do I just need to further reduce the timestep?

cheers,
Ed

Hello Ed,

By increasing the number of layers, you change the modelling. You may have to calibrate it.
