neu_ind : Neumann Nodes

  • Brief description : collects lists of nodes with assigned Neumann conditions at the dofs.
  • File type : fromatted ASCII In Fortran language, the formats for the header and a row of the bulk are '(3i10)' and '(i30)', respectively.
  • Index of the file path in ATLAS.fnames : 10
  • Parameters to be set :
