[Users] Problem with CarpetRegrid2 for changing num_levels via trigger

[Shamim Haque]

Hi all,

I am trying to change the num_levels for CarpetRegrid2 using the trigger,
inspired from the gallery example at ET website. The trigger seems to kick
in at the right place, as the simulation stopped while regridding for new
num_levels.

The dedicated lines in parfile are as follows:





























*CarpetRegrid2::freeze_unaligned_levels =
"yes"CarpetRegrid2::movement_threshold_1    =
0.10CarpetRegrid2::movement_threshold_2    = 0.10CarpetRegrid2::num_centres
            = 2CarpetRegrid2::num_levels_1            = 7
#10CarpetRegrid2::num_levels_2            = 7CarpetRegrid2::position_x_1
         = -13.543564CarpetRegrid2::position_x_2            =
13.543564CarpetRegrid2::radius_1[1]             =
 270.0CarpetRegrid2::radius_1[2]             =
 160.0CarpetRegrid2::radius_1[3]             =
90.0CarpetRegrid2::radius_1[4]             =
40.0CarpetRegrid2::radius_1[5]             =
25.0CarpetRegrid2::radius_1[6]             =
9.0CarpetRegrid2::radius_1[7]             =   6.0CarpetRegrid2::radius_1[8]
            =   3.0CarpetRegrid2::radius_1[9]             =
1.5CarpetRegrid2::radius_2[1]             =
 270.0CarpetRegrid2::radius_2[2]             =
 160.0CarpetRegrid2::radius_2[3]             =
90.0CarpetRegrid2::radius_2[4]             =
40.0CarpetRegrid2::radius_2[5]             =
25.0CarpetRegrid2::radius_2[6]             =
9.0CarpetRegrid2::regrid_every            =
32CarpetRegrid2::symmetry_rotating180    = "no"CarpetRegrid2::verbose
          = "yes"*








*Trigger::Trigger_Number =
1Trigger::Trigger_Checked_Variable[0]="ADMBase::alp"Trigger::Trigger_Reduction
      [0]="minimum"Trigger::Trigger_Relation
 [0]="<"Trigger::Trigger_Checked_Value   [0]=0.1Trigger::Trigger_Reaction
     [0]="steerscalar"Trigger::Trigger_Steered_Scalar      [0] =
"CarpetRegrid2::num_levels[0]" # ==
num_levels_1Trigger::Trigger_Steered_Scalar_Value[0] = "10"*

The outfile reports the following error:







*INFO (CarpetRegrid2): Centre 1 is at position
[0.000191809,0.000291781,-0.00018496] with 10 levelsINFO (CarpetRegrid2):

/home/astro/Documents/ET/Cactus/configs/sim/build/CarpetRegrid2/regrid.cc:89:

number of refinement levels 7*

I could not figure out where it went wrong. The minimum lapse at iteration
4128 is 0.095, so the condition in trigger seems to be working fine. Some
insight into it would be helpful. Thanks in advance.
