This article presents the new light curve, radial velocity curve and broadening functions synthesis and fitting code ROCHE. The modeling is based on the principles originated in Wilson & Devinney (1971). The model also enables analysis of observations of active systems. The cool or/and hot regions are approximated by circular spots. The inverse problem of finding the best photometric elements and spot parameters is solved using the damped differential corrections. Preliminary results for the active contact binary DU Boo are presented.
