Multi-physics Systems Lab is equipped with four 32-node Linux clusters for parallel computing, and other computers for high performance computing. In addition, KISTI's supercomputers are conveniently available for large scale computations. Various in-house codes as well as Abaqus are utilzed together with some postprocessors for finite element analysis. For atomistic simulation, our in-house molecular dynamics(MD) codes and quasicontinuum(QC) codes are employed together with some commercial codes.
