Input scripts for MD(LAMMPS) and CPFE(MOOSE) coupled model to study the effect of process parameters in Additive Manufacturing(AM) process
MD_CPFE_ForAdditiveManufacturing
Concurrent multiscale model developed by coupling Molecular Dynamics(LAMMPS) with Continuum Crystal Plasticity(MOOSE) is used to study the effect of process parameter in defect generation during Additive Manufactirung process.
Features
- Couples Molecular Dynamics with Crystal Plasticity FE.
- MOOSE is used for continum scale modelling and LAMMPS for atomic scale modelling.
- MOOSE is the driver code. LAMMPS is used as library.
- The interface betweem atomistic and continuum is updated periodicaly as material is deposited at the atomistic domain. This keeps computation cost almost constant.
- Right now continuum scale model is only thermo-elasticity.
Simulation results
Featured under development
- Identification, characterization, quantificatrion and transfer of defects from atomistic to continuum as interface is moved.
- crystal-plasticity for continuum. Transport-based CP model will be used as developed in (https://github.com/schakrabortygithub/DiscoFluxM)
