About Non-hydrostatic mode in MOHID

Postby Gerry007 » Tue Sep 26, 2017 01:43

Hi MOHID users and experts,
I am Gerry and using Non-hydrostatic mode of MOHID i.e. the application of three syntax:

NONHYDROSTATIC : 1
NH_ALPHA_LU : 0.1
NH_NORMALIZED_RESIDUAL : 1

What I found was that the model works but the change of the NH features seem to be weird (see below):

NH MODEL - Global Residual : 1.98674E-02
NH MODEL - Number of iterations : 986

suddently to be

NH MODEL - Global Residual : NaN
NH MODEL - Number of iterations : 0

The model still run but this NH MODEL - Global Residual : NaN; NH MODEL - Number of iterations : 0 keep showing on the screen.

I wonder that my Non-hydrostatic is still OK?

Thanks for your attention

Best
Gerry
