Hi Rachel and Support,
I've had an issue with the following a couple of times.
I receive the 'WARNING 2365 - Exceeded top of HQ curve.' and so I either extend my HQ boundary line or use the ‘d’ flag in the attribute column of the 2d_bc layer.
In some cases this works fine. In others, I still receive the warning, but still runs through the simulation to the end. However, when I bring in my results file, the flood levels are concentrated along the QT boundary line.
I suspected it might be to do with the way I merged the ascii files, and so tried merging them in different ways. I have also tried to use 1m grids instead of 2m grids. But with no success. I also adjusted the cell size/time step, and adjusted the 2d_bc layer and 2d_code layer, but to no avail.
Any ideas on why this happens?
Thanks in advance
