sunfluidh:visfield_sunfluidh_file
The old release
The old version of file vifield_s.dat is composed with 12 lines of integer values. This version is still available for people used to the old version of VISFIELD.
- The first two lines allows the user to select a series of files should be converted. The first line is associated to the subdomain number and the second line to the file number which are included in the file name.
- The following line contains one integer value which defines the type of file to convert
- 0 : instantaneous fields : res_yyyyy_xxxxxxx.d
- 1 : statistical fields : rst_yyyyy_xxxxxxx.d
- The third following lines are associated to the grid indices of the computational domain. These index set allows the user to build a space box for extracting only a part of fields from the computational domain.
If one of these index values is set to zero, the whole domain is considered regardless of the meshsize, including the ghost cells. - The following line contains just one integer value for selecting the type of format in which the file will be converted.
0 : tecplot format (.plt) - 1 : VTK format (.vtk). - The following line is a peculiar data related to the vtk format conversion. An integer data defines if the vtk data must be written as a rectilinear form (value 0) or a structured-grid form (value 1).
- The four last lines are reserved to the special case of data manipulation : Please, do not consider them for your work and do not modify them.

The new release
The new version of file, visfield_sunfluidh.dat, allows you to use much more functionalities of VISFIELD, like slice reading. Data setup is organised with the concept of Namelist. All possibilites are described in the example given here.
