<p style="margin-top:0;margin-bottom:0">Hey all,</p>
<p style="margin-top:0;margin-bottom:0"> I am working on the new synchronization in the presync branch, and there's a scheduling comment I don't understand. On line 234 (master branch) of the ADMBase schedule.ccl, the following comment is given before scheduling
a sync for ADM grid functions:<br>

ADMBase variables will need synchronization even when not evolved (eg when a new refined grid appears)</span><br>

According to this, a sync should be triggered in some cases at the mesh refinement stage. Since I don't understand the reasons for this, I can't reproduce this behavior in the new method. Why does the mesh refinement require a sync only sometimes? Is there
a specific scheduled subroutine which creates this behavior, or is it inherent in the AMR process itself?</div>
