Line graphs - header file:

Line Graphics Header File Format.

The line graphics header file contains information about the data files corresponding to the given time. The first row of the file contains five floating point numbers. The second, third and fifth rows contain three integers each and the fourth row contains one integer. The numbers in the sixth through eleventh rows are all floating point numbers. The precise format of each piece of data is not critical, but the ordering of the data is critical. The file contains the following information.

  xmin  xmax  ymin  ymax  time
  nx ny grid-size
  nibpt nps npv
  nxyfs nfs
  nxyfv nfv
  nlinks nmark

Notes:

1.

xmin, xmax, ymin, ymax define the domain size, and time is the current time of the simulation.

2.

nx-vector, ny-vector are the number of grid points in each direction, and grid-size is the grid spacing.

3.

nibpts is the number of immersed boundary points. nps is the number of scalar fields and npv is the number of vector fields defined at the immersed boundary points. These data are in the file linepath/basename.i.xxxx.

4.

nxyfs are the number of grid points with field scalars, and nfs is the number of field scalars in the simulation. These data are contained in the file linepath/basename.s.xxxx.

5.

nxyfv are the number of grid points with field vectors, and nfs is the number of field vectors in the simulation. These data are contained in the file linepath/basename.v.xxxx.

6.

nlinks is the number of links defined in the file linepath/basename.l.xxxx, and nmark is the number of fluid markers defined in the file linepath/basename.m.xxxx.
