I have created a quadrangular mesh of ~1m^2 area elements that I'm trying to interpolate in MIKE Zero (2019 version) Mesh Generator for use in MIKE 21 FM. I have only one scatter data file, a dfs2 file. When I try to interpolate I get an error "unable to triangulate scatter data" or no error message other than "interpolation failed". I have tried with default interpolation parameters, and both linear and natural neighbor. Does anyone have an idea?
Turns out it might be because there are too many scatter points - I'm using a scatter based on a 0.1m x 0.1m elevation raster. Support said that you should use "set values from scatter data" if the nr of scatter data points > nr of elements in mesh. It might also help to save the mesh, close MG and reopen MG before attempting the interpolation because of memory restrictions. Hope this helps someone in the future! If not, then have a nice day.
You may also have very small elements. Try increasing the number of allowed elements by some orders of magnitude. If it works, your mesh will probably be useless, but at least you know the problem and then you can work to do a better mesh.
