Hi Geoffrey and all,<br><br>Including cells if just a piece of them is inside the region does not really change the computation time. It's just a matter of adding or subtracting dx/2 when considering a given cell.<br>
<br>The difference between the two options is mostly academic, I think. I would say it's more important to stick to a consistent definition for all data containers. How are spheres and disks treated? Is it only cell centers there? If so, let's stick with that.<br>

Center would be better I agree, checking if all edges is just multiplying the same calculation by 8.<div><br></div><div>From</div><div><span class="HOEnZb"><font color="#888888">G.S.</font></span><div><div class="h5"><br>

</div>I would say that if the center of the cell is inside the sphere,<br>
include it. I think anything more complicated won't be any better, but<br>
more difficult.<br>
