how to fix this error in simulation.
i'm new to flow 3D

warning from shallow water model:
cell i= 69, j= 89, k= 2, in mesh block 2 is 90% full,
excessive volume error may occur if it fills up completely,
try increasing cell size in z-direction

The shallow water model setup has some specific requirements to make it compatible with 3D mesh blocks. The mesh needs to be 2 cells high, and the bottom cell needs to be large enough to contain all of the fluid. Think of the top cell as a ghost cell... it needs to be there for the model to run but it has no interaction with the fluid.

Check out the user manual for more information on the shallow water model, and then review your mesh setup.
