<p>Dear users,</p>
<p>When I change, Carpet::max_refinement_levels = 5 (instead of 3).
and I also changed,</p>
<p>CarpetRegrid2::num_centres = 1<br>
#CarpetRegrid2::num_levels_1 = 3<br>
#CarpetRegrid2::radius_1[1] = 1<br>
#CarpetRegrid2::radius_1[2] = 1<br>
<br>
CarpetRegrid2::num_levels_1 = 5<br>
CarpetRegrid2::radius_1[1] = 5<br>
CarpetRegrid2::radius_1[2] = 5<br>
CarpetRegrid2::radius_1[3] = 5<br>
CarpetRegrid2::radius_1[4] = 5</p>
<p>My simulation runs successfully. but fourth and fifth levels
shown only nan as follows,</p>

What else should I fix?
