dir_val : Dirichelt values
- Brief description : defines the values of the Dirichlet conditions in time.
- Additional information : to each defined time the values of the Dirichlet conditions at the dofs are assigned.
The times must be defined from the smallest to the largest.
A linear trend for the Dirichlet values is assumed between two consecutive times: at least two times must be present in the file.
- File type : fromatted ASCII
In Fortran language, the formats for the header and a row of the bulk are
'(e20.12,a5)'
and '(e25.12)'
, respectively.
- Index of the file path in ATLAS.fnames : 9
- Parameters to be set :
