Hello Foamers,
Iím working on the waveExampleSolitary tutorial by OpenFoam v1806.
But the tutorial crash when I change the mesh. The new mesh is conducted by ICEM.
The computational domain is attached.

The error message is:

mpirun noticed that process rank 0 with PID 0 on node ryou-virtual-machine exited on signal 8 (Floating point exception).

I guess this problem is due to wrong definition of setFieldsDict, because the water.alpha of initial inlet seems to be weird, as attached figure shown.
The setFieldsDict is defined as using the new mesh:

Code:
defaultFieldValues
(
    volScalarFieldValue alpha.water 0
);

regions
(
    boxToCell
    {
        box (0 0 -0.1513274595) (15 1 0.1513274595);
        fieldValues
        (
            volScalarFieldValue alpha.water 1
        );
    }
);
Any suggestions are appreciated.
Thank you.
