## Limb (k) is starts swing at time (t) with parameters (F0), (kv), (Gu) and (Tsw);
## it has velocity (vv), stance time (ttst[k]), previous swing time (ttsw[k]) and duty factor (dutyfactor).

## simulation data saved as: 1 (k),  2 (t),  3 (F0),  4 (kv),  5 (Gu),  6 (Tsw), 7(vv), 8 (ttst[k]), 9 (ttsw[k]), 10 (dutyfactor)
