Dear Professor,
Hello! I'm simulating a scour of an undersea pipeline but there are some problems. The model stops automatically whenever sediment is counted. I found out it has something to do with S43. When the default value of 1000 is reached, the model iterates to 1000 steps to stop the calculation.
