The smoothing lengths for the tracers are found in a round-about way right now that is less than ideal. Is there a way in yt to create smoothing lengths using just particle coordinates like this? (IE the complex nearest neighbor math I would rather not code myself if I don’t have to)</div><div><div class="bloop_container"><div class="bloop_frame"> </div></div></div><img src="cid:7E01FD91-6ACD-42C0-9802-A3CA8344AF86"><br><div id="bloop_sign_1407513093957509120" class="bloop_sign"><div style="font-family:helvetica,arial;font-size:13px"><br></div><div style="font-family:helvetica,arial;font-size:13px">Thanks,</div><div style="font-family:helvetica,arial;font-size:13px"><br></div><div style="font-family:helvetica,arial;font-size:13px">Amos M</div></div></body></html>
