Multiscale Dislocation Dynamics Plasticity (MDDP) is a discrete dislocation dynamics (DD) model for crystalline materials coupled by finite element (FE) analysis developed by Hussein M. Zbib and colleagues .
MDDP simulations can run for calibration of data upscaled from atomistic scale calculations. It is run from an executable and requires two input files. For example, for modeling crystal plasticity in aluminum, the code MDDP can be used to calibrate values of dislocation mobility determined from molecular dynamics simulations. Stress-strain curve data can then be used to upscale to the mesoscale crystal plasticity length scale  .
For additional information regarding MDDP, please view the MDDP Manual.
Tecplot  is a post-processing software that can be used to view MDDP simulation outputs. It can be used to view the evolution of the dislocation structure, as well as produce curves, such as stress-strain curves. Step-by-step post-processing information can be found here.
