An example usage of profile function 5b.

#include "grid/octree.h"    // Octree is 3D
//#include "grid/quadtree.h //<- Using a 2D grid gives identical results for this example
#include "profile5c.h"

scalar wave[], height[], lev[];

int main(){
  init_grid (1 << 5);
  L0 = 2.*M_PI;
  refine (level < 7 && ((y + x/3.) < 3.));
  foreach(){
    wave[] = 2.*sin(y) + 3.;
    height[] = y;
    lev[] = level;
  }
  profile ();
  profile (fname = "equi", n = 10);
}

Result

The code above prints to stdout, whos content are plotted below using an automated script:

datafile = 'out'
firstrow = system('head -1 '.datafile)
set yr [-0.5:8]
set xr [-0.5:7]
set ylabel word(firstrow, 1)
set key autotitle columnheader box on
set size square
plot datafile u 2:1 t 'wave' ,\
    datafile u 3:1  t 'y',\
    datafile u 4:1  t 'level'

Adapive (script)

The content of the file “equi” is also plotted:

datafile = 'equi'
firstrow = system('head -1 '.datafile)
set yr [-0.5:8]
set xr [-0.5:7]
set ylabel word(firstrow, 1)
set key autotitle columnheader box on
plot datafile u 2:1 t 'wave' ,\
    datafile u 3:1 t 'y' ,\
    datafile u 4:1 t 'level'

Equidistant profile for 10 heights (script)

We are happy with the result as it shows some minimal consistency.
