How to for relax_disp
- Run 'dx',
- Click on 'Edit Visual Programs...',
- Select the map.net program created by relax,
- Select the menu entry 'Execute->Execute on change'.
That's it.
You now have a 3D frame, but nothing in it.
Therefore the contour levels must be too low or high.
From the map file, the values are in the hundreds of thousands.
Then:
- In the main program window, double click on the 'Isosurface elements'.
- Change the values until you see surfaces. In the first the value is 500. I changed this to 500,000.
- In the second, 100 -> 100,000.
- In the third, 20 -> 20,000.
- In the last, 7 -> 7,000.
This should maybe be performed by the dx.map user function, determining reasonable contour levels.
With a bit of zooming, clicking on 'File -> Save image' in the "Surface" window, "allowing rendering", and outputting to a large TIFF file, "save current", then "apply".

Note that for a good resolution plot, you will need many more increments.
Using the lower and upper dx.map arguments will be useful to zoom into the space.
