Michelle 0 Posted March 27, 2020 Report Share Posted March 27, 2020 (edited) Hi everybody I am new to SMS-TUFLOW. I am having some problems with the model as every time when I delete or modify the boundary of the model, the model become unstable. For example, in this model, it ran smoothly before. But when I added two more polygon in the material, when I run it, the error pop up and said the Tuflow model is unstable. I checked the error message and it said "Negative V depth" "Negative U" . I have the feeling I need to do some extra steps when I want to modify the boundary because when I rebuilt the model again with the extra polygon, it ran smoothly. Could some one advice me how to fix this problem because I cannot just rebuilt the whole model when I want to modify something. Thank you for your time Edited March 27, 2020 by Michelle Quote Link to post Share on other sites
