Generate tide from water level

[allorens@intercontrol.es]

Hi mohiders,

I'm trying to launch a simulation with a tide in the open boudary, from a time serie with the water levels. I've been looking at the topics, and I've found that it's possible. The problem is I write the files as you specify in the forum, but I get the following error:

Data File does not exists : Harmonics
ModuleEnterData - ConstructEnterData - ERR02

My tidal components file is:

<begingauge>
NAME : Ejemplo
METRIC_X : 734132.1
METRIC_Y : 4394635
REF_LEVEL : 1.000
EVOLUTION : Time Serie

TIME_SERIE_LOCATION : C:\\Documents and Settings\\allorens\\Escritorio\\MOHID\\GUI\\GeneralData\\waterlevels.dat

DT_SERIE : 600
<endgauge>

And my waterlevels file is:

Dou you have any idea about what is it doing?

Thank you,

Hi Ana,

According with the code, apparently the error arises because the MOHID Water does not finds the tide components file. Have you provided it in MOHID GUI?

Please check if there is not an error in the name/path of file.

Best regards,

Angela

Hi Angela,

I've checked in the properties chart of the simulation, and I have the tidal components file, so I can't understand why it happens. Also, if I change the tidal file and I introduce harmonics, the model can run.

Do you have any idea about the error?

Thank you again,

Ana.

[acanas.maretec@taguspark.pt]

Hi Ana,

That is very strange because the error is registered in the code has the file not existing ...

In that case, try with a file as you have (with water level time serie) but with indication of harmonics with null phase and amplitude.

Let me know if this works.

Best regards,

Angela

Hi Angela,

The problem continues. They only way it goes is when I set in EVOLUTION: Harmonics, so in that case the time serie with the waterlevels.dat doesn't go.

I don't know how I can solve the problem, can you help me?

Thank you,

Ana.

Hi Ana,

The problem is in the keyword defining the time series file of water elevations. You're using TIME_SERIE_LOCATION when in fact the keyword is TIME_SERIE_FILE.

To see a description of all keywords in MOHID organized by module please login at MOHID website and go to http://www.mohid.com/ihs/

Hope this helps,
Luis

Hi Luis,

I've changed the files and I continue trying to generate tide from the water level but I can't do it. My files are the following:

Can someone help me ?

Thank you,

And another thing...I run the model with a tide generated from harmonics and it runs, so I cann't understand what it's happening.

Ana.

[luis_at_mohid.com]

Hi Ana,

Only in this case (tide gauge time series) the time series time step has to be consistent with the keyword DT_SERIE present in the gauge input data file.
In your case you have:

TIME_UNITS : HOURS

and you have a time step of 1 hour (3600 seconds), so the DT_SERIE keyword in the gauge input data file should be set to 3600.

DT_SERIE : 3600

Hope this helps,
Luis

[allorens@intercontrol.es]

Hi Luis,

The problem continues, changing the DT_SERIE to 3600.

What can I do?

Thank you,

Ana.

Hi Ana,

Hi,

When an error like this:

forrtl: error (72): floating overflow
Image PC Routine Line Source
MohidWater_Intel_ 0096207C Unknown Unknown Unknown
MohidWater_Intel_ 009620BC Unknown Unknown Unknown

MohidWater_Intel_ 009795E6 Unknown Unknown Unknown
MohidWater_Intel_ 00960715 Unknown Unknown Unknown
kernel32.dll 7C817067 Unknown Unknown Unknown

occurs you can use a different executable to traceback the error. Go to MOHID GUI, Tools, Options and change the MOHID Water executable path to

Quote:
C:\\Program Files\\Mohid\\MohidWater_Intel_Single_Traceback.exe

Then run the model again and post the new error message, that this time will contain the source code line where the model \"crashes\" and this way we'll be able to help you.

Best regards,
Luis
