A FETI-like Domain decomposition dedicated to Contact Dynamics is considered here, especially concerning "corner grain" treatment and its influence on the numerical simulation. Moreover, parallel implementation of Non-Smooth Contact Domain Decomposition (NSCDD) using MPI library is studied as regards of load balancing and computing performances, leading to motivate time homogenization techniques.
