Hi, 

I made a 1D model of a river. In order to model how floods along the river will develop, I want to add 2D grids at 6 different locations. Below I show how I tried to do this. 

1. I made the 1D model in D-HYDRO 1D2D. 
2. I open the 2D tab and select 'grid'. Then I click on 'Spatial Operations' and import 6 different bedlevel samples (.xyz files). 
3. I click with right mouse on 'Grid' and import the first 2D grid (created in RGFGRID by growing a grid from polygon and exported as U-GRID).
4. Then I click on 'Copy to spatial data' and finally on 'Interpolate'. Then I generate links between the 1D and 2D model and run it. 

However, this only works when I do it for one of the 2D grids. When I try to repeat this process, the interpolation button is disabled or the first grid dissapears again. Is it somehow possible to generate the model like this? 

I tried creating a combined grid in RGFGRID that includes all the six grids, but also then, just one of the grids get uploaded. 

Does anyone have a tip on how to solve this?
