Monika 0 Report post Posted March 11 Hello All, I am trying to run a river model in TUFlow by building mesh with SMS. The following error comes when I try to run it. " Negative area calculated for cell 1824" . Please help me with your valuable suggestions. Thanks in advance Quote Share this post Link to post Share on other sites

Monika 0 Report post Posted March 11 Hi Donald, Thank you for your reply. I am attaching the picture of the particular cell. (The red marked one) Thanks Quote Share this post Link to post Share on other sites
Donald Hendon 0 Report post Posted March 11 There is a couple of things I would try. One thing is I would delete the element and the ones nest to them, and then draw them back manually. Another is changing your boundary shape. Does it need to have that point? Let me know if this helps! Quote Share this post Link to post Share on other sites
Monika 0 Report post Posted March 11 Hi Donald, I have tried to delete this and its neighbouring elements. Then it shows the same error with another element not very near to it. Also I really don't understand what they mean by negative area. Thanks Quote Share this post Link to post Share on other sites
Donald Hendon 0 Report post Posted March 11 hmm, I am not sure what it means either. I have never had that error, but it has been a while since I worked with TUflow. Make sure your elevation data extends beyond your mesh domain. You can keep redrawing the elements shown as negative until you cover them all. You could regenerate your mesh with a new domain. Renumber your elements. Sorry I can't be more helpful. Quote Share this post Link to post Share on other sites
