Description
Hello,
I was testing if I could fill my entire domain with a field probe. However, as my domain is rectangular on one axis the field probe plane extended beyond the simulation domain boundary. In this case I get a SEGFAULT when attempting to write out the FieldProbe reduced diagnostic. However, there is no useful information in stdout or stderr to point to this issue. I've attached the Backtrace I received too which doesn't show much. Note: I ensured the FieldProbe was confined within the simulation domain and the simulation had no errors.
It might be worth adding some check of the field probe parameters before the simulation starts to raise an error.
Cheers,
Daniel
=== If no file names and line numbers are shown below, one can run
addr2line -Cpfie my_exefile my_line_address
to convert `my_line_address` (e.g., 0x4a6b) into file name and line number.
Or one can use amrex/Tools/Backtrace/parse_bt.py.
=== Please note that the line number reported by addr2line may not be accurate.
One can use
readelf -wl my_exefile | grep my_line_address'
to find out the offset for that line.
