open TELEMAC-MASCARET The mathematically superior suite of solvers

Has any expert ever used channel mesh to create a mesh for the river in Blue Kenue? After using it, Telemac encountered an error when running, but I couldn't find the reason. Using density in t3 mesh to encrypt the river is fine and can run normally. Can someone help us? Thank you very much

Here is my error message：

GEOELT: ELEMENT 14442 : NEGATIVE DETERMINANT
This indicate a problem in your mesh.
Check it in BK (all element should be CCW)

Thank you very much for your reply. I am a beginner and although I found the element 14442 in bk, what should I do with this element? The grid was generated in bk and I did not manipulate any elements. Why did this non ccw element appear? Or, what should I do with the error grid? If you have time to reply to me, I would greatly appreciate it

And after my inspection, I found that the three points that make up element 14442 are indeed sorted counterclockwise

Maybe you could join the files to let other users to test, check and potentially help you.
You could also try to use the check mesh option in Telemac

By the way, according to statistics, I would say you could enhance your mesh because 14 neighbors is really too high

Haha, thank you very much. Perhaps it was my low-level mistake that caused this issue to occur. I will carefully consider your suggestions and try to debug my problem. Thank you again

There are two or three nodes among the 14 neighbors, which appear at the intersection of channel mesh and t3 mesh

Hi
Please start with reading the forum rules. No precise information about the problem doesn't let other users to help you...
Encountered error is not necessarily related to the river mesh in BK.
Look at the baxter tutorial could help you to solve your problem

Regards

Thank you very much for your reply. I will attach my error message. Best wishes
