Help

Here is my situation. I have two dams next to each other, I called them GF-2 & GF-3. I managed to get GF-2 working perfectly. Because these dams are next to each other, i figured the results would be very similar. However, I would need to change the first 5 cross sections of GF-2. Because after the 5th cross section GF-3's inundation path would follow GF-2's inunadation path.

Here is my problem, I go to change some minor cross section heights and lenghts, say GF-2 had a cross section at 1465 ft MSL and GF-3 had a cross section at 1470 ft MSL. But for some reason this minor change is giving me all sorts of problems.( non-convergence errors, floating point etc.. )

And another problem I found, was when I changed the cross sections lenghts. In my problem GF-2 is longer than GF-3. So when i go to shorten the lenghts I get the same errors. Now i know the dam lenght is only so long so I can't go making it longer... inorder to get the program running. This would not be practical, nor would I be simulating what's accually out there. I'm starting to loose faith in this program. There is no way that something so small should cause such proplems. Is there anyone out there that can give me some advice(without charging me $450 US for 2 hrs work) as the someone at one of the BOSS DAMBRK offices did.

Thank you
Dave
