    • An atomistic/continuum coupling method using enriched bases 

      Chen J.; Garcia-Cervera C.J.; Li X. (Multiscale Modeling and Simulation, 2015-12-31)
      A common observation from an atomistic to continuum coupling method is that the error is often generated and concentrated near the interface, where the two models are combined. In this paper, a new method is proposed to ...
    • An efficient multigrid strategy for large-scale molecular mechanics optimization 

      Chen J.; García-Cervera C.J. (Journal of Computational Physics, 2017-08-01)
      Static mechanical properties of materials require large-scale nonlinear optimization of the molecular mechanics model under various controls. This paper presents an efficient multigrid strategy to solve such problems. This ...
