Problem with connection 1D/2D: forrtl: severe (151): allocatable array is already allocated

[dadinho17]

Hello everybody. I have a big problem and i cannot connect the model 1D to 2D. I’ve already tried to run the steady flow in 1D mode without 2D area and it works. After i added a 2D area(as a lateral structure) and i have connected it. Then i tried to run the steady flow in 2D and it give me this error:

Anyone can kindly help me?

I would check the Lateral Structure editor. Might help to post screenshots of that, as well as the Geometry editor zooming in on 1D + 2D elements

No idea if this is the issue but I’ve seen this type of error report when I had deleted a boundary condition line in the geometry but the flow editor still had the BC listed.

You can not run a steady flow with a steady flow. You have to have a unsteady flow. This unsteady flow can be a constant flow and if run long enough, would act like a steady flow model.
