Hello,

I would like to integrate the laplacian of temperature over z :

foreach()
shadow[] += ((T[1,0,0] - 2.*T[] + T[-1,0,0])/sq(Delta) + (T[0,1,0] - 2.*T[] + T[0,-1,0])/sq(Delta)) * Delta;

How do I say that I want to integrate only on z with basilisk iterators?

Thank you,

Alexandre

Hallo Alexandre,

You can integrate along a line segment using "foreach_segment()". e.g.,

If you want an "integral field" of some sort, you could look (past all the errors) here,

and notice that the segment integral is likely more robust.
