- In the first simulations we examine a cello
string, with
bending stiffness
N m
.
- The string, starting from rest, is excited by a constant bow
velocity
m/s.
- The Schelleng diagram is computed by varying the bow force
from
to
, and the normalized distance
of the bow from the bridge is varied between
and
(where 0.5 would be the middle of the bow).
- A classifier routine examines the shape of the established waveforms.

In the second simulations we fix the bow position to , where 0 represents the bridge while 1 represents the nut, and we vary bow velocity and bow force.
