ADCIRC with non-periodic normal flux boundary

Recommended Posts

Hi,

Now I'm using ADCIRC to simulate the inundation with a non-periodic normal flux boundary( the file of fort.20).When I ran the model,I found that when the QNIN(the data in the fort.20) was larger than 22 the running would terminate before finishing.Because the QNIN =Q/the width of river,If I set the Q smaller than the measured value so I could not get the expected elevation which was recorded in the file of fort.61.Although I could obtain the file of fort.61,but during the running it always appeared "ERROR: Elevation.gt.ErrorElev" and the simulated elevation usually was dozen meters which was obvious wrong.

I don't know where is the error and how should I do to resolve this problem?I have smoothed the grid that every one is close to regular triangle and this grid can do well with the simulation that wind is the exclusiv forcing term.

Hi,

Have you checked to see whether the inflow through the boundary is what you are specifying? I found that adcirc didn't get fluxes right for the pipeflow wier boundary condition and so it may have a problem here as well. Specify a flux that runs without the errors and then check in the results that the actual flux is what you put in. If the flux turns out to be much greater than expected then you will have to edit the code to correct this error.

Hope this helps a little

Hi Ian,

I don't know how to check the inflow flux.I didn't find the parameter which controlled to export the flux of specified flow boundary in the file of fort.15.How do you realize it ?

Thanks.
