I made a new model with whole area 2D and this problem is solved, but I still don’t know why in 1D/2D model water flow was like that.

Another problem after I check the all 2D model is that velocity in channel is very strange when flow increase. After reach a certain flow, the problem disappears. I have tried larger cell size but didn’t solve the problem. Anyone can help?

I just create a new project and import geometry from old model, then it works.

I received the 1D model from another engineer and added 2D areas based on that, so less change on 1D part would be good. Just want to know other options to solve this problem if there is.

You are right. Length of lateral structure and centerline is different. Now it’s working.

Thank you, Scott.

Thanks Scott,

I know the station is not correct, but it is computed by the software, I don’t know how to fix it. I checked my 2D mesh, tried to change a little bit of weir location, still couldn’t work.

I know the lateral structure should ends Xs 3916, but it’s Xs 3901.
