[Users] init_3_timelevels on Latest stable ET

[Yosef Zlochower]

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]

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.
