Hi Marwan- It looks like you are trying to overlay a 3D field on a 2D topography, thus the error about the domain dimension mismatch. Could you please upload a sample file to: http://motherlode.ucar.edu/repository/alias/idvupload and let me know what fields you are using for the winds and topography.
