Select particles on the surface

I am trying to output the atoms at the surface of the thin film to calculate the root-mean-square (RMS) surface roughness.

It shows in the ovito manual that there is an option named "Select particles on the surface" in "Construct surface mesh" which can help use find the surface atoms. However, I can only find "Construct surface mesh", but cannot find "Select particles on the surface".

Does anyone know how to do that? Many thanks!

Dear Yang Li,

have you upgraded to the latest OVITO version? It looks like you’re using an older version that doesn’t have the “Select particles on the surface” option yet.

Hi Constanze,

I found it after downloading the latest version. Thanks a lot!
