Grid and bathymetry

Postby deeptha@ktr.srmuniv.ac.in » Thu May 12, 2011 11:03

Hi, is it necessary to have one bathymetry value for each grid cell? I am trying a rectangular channel, but not able to interpolate the bathymetry values beyond the given xyz data. Can someone show me how to get the bathymetry for the data below?

Thanks,
Deeptha

Hi,

Using the MOHID GIS Digital Terrain Creator (http://www.mohid.com/wiki/index.php?title=Mohid_GIS#Create_Digital_Terrain) or the new MOHID Studio you can generate a bathymetry using the xyz, grd and xy files.

Best regards,
Luis

Hello Gustavo,

is this a post on Digital Terrain Creator Tool or MOHID simulation?

That error seems that you did not defined a bathymetry for the run. The line "IN_BATIM" exists for example in nomfich.dat file in exe folder (the file that handles all the paths needed to run the simulation). And in this case probably is empty, because it was not defined in MOHID GUI or MOHID Studio.

Nevertheless, you can define it with the graphical interfaces (MOHID GUI or MOHID Studio) or editing the file (text file) and adding the path to the bathymetry file.

Best regards,
David

Thank You
the error appears during a test simulation in Mohid Studio
I intended to edit a save the Nomfich file to put the Batim file path, but marks the same error and the file is erased in the line IN_BATIM and appears
newly in blank.

ERR01 ModuleEnterData

Where can I indicate the path ?

thanks in advance
Gustavo

Dear Gustavo,

you have to specify the path at the properties of the "Domain".

Dear Gustavo,

in this place you have to place the bathymetry data file (a "Grid Data"). It can't be a "Grid" file.

The Wiki says about the horizontal grid the next:

Module HorizontalGrid manages all the information in MOHID regarding the horizontal discretization of a simulation domain. This information is read from a grid file.

I read that the grid data file must to start in a first value of zero and the acumulate its values.
but where may a have to put the file ?
the file must contain BeginData2D, EndData2D, BEginXX, EndXX, BeginYY EndYY?
thanks for your patience
Gustavo

I found the source of error in the UTM ZONE projection
but now the error changed from error 150 to error 140.
thanks

From your description I can't figure out what the problem might be...

Can post a more detailed description of the error, please?

Hi. After converting the coastline(.kml) file to a polygon(.xy) file using kml2mohid.exe, I tried to open the polygon(.xy) file using MOHID GIS, but it shows the following error.
"Invalid Polygon file format". My polygon file looks like this:

Try to remove the blank line before the "<endpolygon>" tag.
