<div style="direction:ltr"><span style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)"> the perfectly cut away may be due to the fact that you may have had failures in
con2prim on the finest levels (and maybe points got set to atmosphere), but the coarser levels were not computed yet. Your standard output reports indeed errors in c2p. You use 6 refinement levels and therefore all levels are at the same time every 2^(6-1)=32
iterations. At iteration 4 only the 3 most inner levels would be at the same.</span></div>
