With the recent ADFtrain functionality, it is easier to build up your training data and parameterize ReaxFF.
November 2018 workshops
In this 1-day hands-on advanced workshop we will use CMA-ES to refine an existing ReaxFF force field for epoxy polymers (see also bond boost for cross-linking polymerization with ReaxFF and mechanical properties of epoxy polymers).
For time considerations we will train the force field with DFTB, but training data can be similarly obtained with our molecular and periodic DFT codes ADF and BAND. The hands-on slides and reactive force field fitting package (training data, inputs) used for the workshops given in October 2018 have been tested with the ‘fix binaries‘.
The project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 764810 (S4CE).
