I can only get this to work on the example file everything else gives me this 1. Solution exception:expected float, got list? Any clues as to what the issue is?
No idea what might be causing this issue, try with another DEM you know has a steep topography just to test the plugin is working properly, otherwise there is an issue with the raster (the file format perhaps?)
Damn, my file was 1GB and it took about 15 minutes to import. However I get an error that number of dimensions are outside the supported area. I tried both 10,000 and 10. My model space is mm.
