Open Source Software

Dr. Prakash a co-author of multiple software packages that are now made available open-source to the scientific community. Only a brief overview is provided here.

  • nanoSCULPT
    nanoSCULPT refers to a methodology and software tool to create complex and realistic structures for large scale atomistic simulations from arbitrarily shaped 3D datasets. Please visit the nanoSCULPT wiki for more details on the tool.
  • FE2AT
    FE2AT stands for Finite Elements 2 ATomistics and is essentially used to perform finite element informed atomistic simulations, i.e finite element calculations are used to provide appropriate initial and boundary conditions for atomistic simulations. Please visit the FE2AT wiki for more details on the tool.
  • IdentiPy and Parldent-VPSC
    IdentiPy is a software tool that enables the identification of material parameters for finite element simulations with Abaqus. A variant called Parident-VPSC (PARameter IDENTification for VPSC) has also been programmed for identifying Voce-hardening parameters for simulations with the standalone Visco-Plastic Self-Consistent model. Both IdentiPy and Parident-VPSC are open source and made available upon request.
