Program Exception - access violation

Postby johannesjanzen@gmail.com » Tue May 15, 2012 19:48

Hi,
i´m trying to run a simulation about a river in Brazil, i generated the digital terrain model in Mohid GIS and the first time i ran the simulation it said that it had changed my terrain file since it contained isolated horizontal cells, the program itself generated a new terrain file (.new2), i opened it and copied the information within it into a new file and saved it to be my new terrain file (i also ran it with the exact same archive that mohid gui generated for me and the same following error occurred), i ran the mohid gui with the MohidWaterIntelTraceback.exe extension and now this is my error:


C:\Camila\RESAN\pesquisa_oleo\_projeto\GUI>copy "C:\Users\camila\Desktop\Mohid p

Hello,

I've noticed that this error occurs when I have something very wrong with the input files, particularly with bathymetry. For example, I had it when by mistake I set a path to the old .dat file instead of normal bathymetry, or when I had in my bathymetry the coordinate system not defined or wrong.

Check if you have correct Coordinate tip, corresponding to geographic or projected coordinates, correct UTM zone, latitude, longitude, origin etc.

Good luck!
Nadya

Hi,
I noted that you have a lot of key-words in your hydrodynamic input file.

But Ok, let me tell my point:
- in the bi_harmonic I think you are using a big value, here is the link that teach how to set the proper value of the biharmonic coef.
http://www.mohid.com/wiki/index.php?title=Biharmonic

- generally in my simulations, these erros were related with the bathymetry (check you results by changing the output to the time step), probably you'll
see where are the cells with the erros... and you'll have to ajust your bathymetry...

Well this is my point.

Leonardo Carvalho.

**Abraços e boa sorte em suas simulações!
