Lateral coupling: between sequential 1D and 2D domains
Good afternoon.
I have 5 sequential 1D domains in my simulation and now I want to lateral connect the third one with a 2D mesh which should be the floodplain. In the error file there's no error, but the simulation doesn't work. When I run the .bcm there's open a grey window which report: "Generic warning: In Y:\buildtrees\vtk\src\ad8774e85e-85de89847a.clean\Rendering\Core\vtkTexture.cxx. line 32
Error: no override found for 'vtkTexture' ".
This is my command file:

}Could anyone help me?
Furthermore I need to start the 2d domain with initial type=dry
but the 1D domains need initial condition continue, so the time start simulation are different and this will be an error. How can I do?
Kind regards

Re: Lateral coupling: between sequential 1D and 2D domains
Hi
The error message is not related to the coupling-setup of the model, but to the SPECIAL_OUTPUT of type BASEviz. BASEviz seems to be affected by a bug in version 2.8.1. This will be fixed in the next release of version 2.
Best
