I was simulated as like below(hydrodynamic_1.dat), but output result was
first 3 or 4 time_output, next and to the end of rsult had no velocity

Hi,

To answer your questions I have to post three more questions:

Are you sure that MOHID program did run until the end?
Did you take a look to the waterlevel to see if it makes any sense?
What is the size of your grid cells? I'm asking this due to the high BIHARMONIC_COEF you are using...

Grid cell interbal : 200meter
i=1 to 238
j=1 to 450

biharmonic coef is not defined

Cycle Boundary Explicit was not checked

Dt output : 600sec

Simulating Time : One days

And I aske another: Consumming Time of workOut for onedays is too much(about 6hrs My computer is 2.8Gh CPU, and 512MB memory)

Hi,

from the data file you posted in the forum, the model should output results in HDF files every 10min. (Keyword OUTPUT_TIME). this process can be quiet time consuming....

No time series will be printed, since you do not define where (in your file are missing blocks like:

<BeginTimeSerie>
LOCALIZATION_I : 30
LOCALIZATION_J : 10
LOCALIZATION_K : 1
<EndTimeSerie>


In order to help you, can you please send me all your data files, so I can take a closer look to what is happening?

Frank
