open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,
I am using some scatters to assign values to bottom friction in slf file, these scatters include x, y, n. First I created a new selafin in bluekenue, then added bottom and bottom friction, then interpolated each of them using 2d interpolator. Below is a picture of my slf file, (x, y, n) scatterplot, with variation present in bottom. But at the end of the run in telemac-2d, the bottom in the output slf file changes a lot from the input bottom. But theoretically this should not change. These changes cause anomalies in the simulated data, what should I do now? Perhaps there is some error in my operation in giving the bottom friction? Here I will upload the preprocessed slf file and the exception that occurs.

Unfortunately, there are no attachments to your post so I cannot test anything in Blue Kenue in order to see if Blue Kenue has a fault.

Kindly... Alan
