Can Bison components apply any meshes?

Hi! I am trying to find a way to do terrain analysis.

When I searched on Youtube, most people used Bison, so I downloaded it and tried it on my mesh terrain such as flow and concavity. However, none of bison component work at all and I assume that is because I did not create my mesh from XYZ acs-file, or tiff file. My mesh terrain is from contour line that I’ve drawn based on 2D map on the site.

Can someone advise me or let me know what is the problem that I cannot use Bison components?

Super thanks!
