connecting reach and 2d area with lateral structure

[Anonymous]

Hi,

I have a problem connecting 1d river reach and 2d flow area with a lateral structure. Every time I try to do it I get this error :

forrtl: severe (151): allocatable array is already allocated
Image PC Routine Line Source

Error with program: RasSteady64.exe Exit Code = 151

I’m trying to do a steady flow analysis. I’m new to the combined 1d/2d modelling. So I’m probablly doing something wrong. Can anyone please help me?
Thank you very much.

I don’t think you can do a steady 2D model.

If you want to have a 1D reach connected to a 2D area, run it in unsteady.

I obtain the same error as Uros.
Nevertheless, I cannot find in the reference manual that it’s not possible to run a steady 1D-2D model.
Any idea about where I can find more information about this?

to run a steady model in 2D you just need to change your hydrograph to have a constant flow for a long period.
