Hi, If I use the carpet::init_3_timelevels=yes I get the following error WARNING level 0 in thorn CarpetLib processor 0 host quasar.ccrg.rit.edu (line 385 of /home/yosef/ET/Maxwell/Cactus/configs/lazev/build/CarpetLib/gdata.cc): -> Internal error: extrapolation in time. variable=ADMBASE::alp time=1280 times=[2560,4955,2395] WARNING level 0 in thorn CarpetLib processor 0 host quasar.ccrg.rit.edu (line 385 of /home/yosef/ET/Maxwell/Cactus/configs/lazev/build/CarpetLib/gdata.cc): -> Internal error: extrapolation in time. variable=ADMBASE::alp time=1280 times=[2560,4955,2395]
This error message did not occur when I ran with the previous stable ET version.
Here is a short parfile with no physics thorns that displays the problem.
