MAXIMUM COURANT NUMBER = 1.000E+00 AT CELL 14 MEAN COURANT NUMBER = 5.300E-03

*** WARNING #052 *** INITIAL RESIDUAL BELOW ROUND-OFF ERROR LIMIT SOLUTION ,EQ: VMOM

*** WARNING #052 *** INITIAL RESIDUAL BELOW ROUND-OFF ERROR LIMIT SOLUTION ,EQ: WMOM How can I make it ?Thank you !

Those are warnings, not errors. They mean that there is nothing to solve for VMOM and WMOM. Most likely there is no movement at all in those directions, and zero is the correct solution, at least at this stage of the calculation.

I would only worry if this continues for the whole length of the simulation, and even then only if this is not what you expect. If you solve for the third dimension velocity in a two dimensional case, for example, this will continue, but it just means that you should have switched off calculation of the third velocity. Nothing wrong with the solution, but you wasted a bit of RAM.
