Dear users,
I want to fixed my atoms during MD simulations. As my previous email , I
needed your help to MovedAtoms options If I were doing smthg
missundderstood.
Here is my programme to chose with 196 atoms in SCC=Yes and SCC=No. It
warned me to ignored the options MovedAtoms. On the contrary to
http://www.dftb-plus.info/about_dftb/snapshot_081217/ Atoms can be fixed
during MD:The MovedAtoms option can be set during MD to only allow a subset
of atoms to move , I should able to fixed my atoms. Here are errors listed
below.
Thank you for your interest.
