• MIKE SHE Interpolation Error from domain

    I am relatively new to MIKE SHE, so it might be a easy one. I am using shape file to define model domain and grid. When I preprocess the data, it says missing value in dem file to generate value for  domain cell. I tried converting the prepared dfs2 file of topography to shape file and reclassified the shape file to single polygon. The problem still exists while using the generated shapefile.
    I will be highly grateful if anybody can help me out.
