<div dir="ltr">Francisco<div><br></div><div>There is no respective reduction operation in Cactus. What you can do is to create a 1d array for the values in the z direction -- on each process --, initialize it to zero, and then add this process's local contribution to that array. Cactus then has a "1d local array reduction" function that you can call, which calculates the global result.</div><div><br></div><div>-erik</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Mar 29, 2017 at 8:24 PM, Francisco Guzman <span dir="ltr"><<a href="mailto:guzman@ifm.umich.mx" target="_blank">guzman@ifm.umich.mx</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font-family:arial,helvetica,sans-serif;font-size:12pt;color:#000000"><div><br></div><div>Dear all,</div><div><br></div><div>Assume I have a thorn mounted on Carpet, completely unrelated to any GR thorn (say my_wavetoy) .<br></div><div><br></div><div>Is there a way to estimate the integral of a grid function on every slice of z=constant?</div><div><br></div><div>This reminds me the outflow thorn that is capable of estimating the integral of fluxes (grid functions) across a spherical surface.</div><div><br></div><div>I wonder whether there is something similar to integrate a flux (a given grid function of my choice) across z=constant planes:</div><div><br></div><div>- perhaps a reduction operator from Carpet</div><div>- a similar thorn to outflow</div><div><br></div><div>Thanks in advance,</div><div>Francisco</div><div><br></div></div></div><br>______________________________<wbr>_________________<br>
