Distributed Nonsmooth Contact Domain Decomposition (NSCDD): Algorithmic Structure and Scalability

Numerical simulations of the dynamics of discrete structures in presence of numerous impacts with frictional contacts leads to CPU-intensive large time computations. To deal with these problems, numerical tools have been developed, such as the nonsmooth contact domain decomposition (NSCDD). We present further a distributed version of its algorithm with parallel detection of fine contacts and discuss two possible communication schemes to solve the interface problem. Those improvements allow to study scalability and numerical performances of the method for 2D and 3D granular media.
