PorousFlowEnergyAccumulator

accumulate the produced thermal energy

Description

PorousFlowEnergyAccumulator accumulates the produced thermal energy of a doublet system. On every timestep where the supplied ProductionIndicator postprocessor is greater than 0.5, the sum of the hotwellenergy and coldwellenergy postprocessors is added to a running total; timesteps where the indicator is at or below 0.5 (e.g. during an injection-only or idle season) do not contribute. The comparison is against 0.5 rather than an exact equality test with 1 so that a smoothed or transfer-round-tripped indicator still registers. The postprocessor value reported is the absolute value of the running total, so it grows monotonically over a simulation dominated by production.

# Darcy flow with heat advection and conduction
[Mesh]
  # The original base_final_50.e had one or more element-block IDs that overflowed the
  # unsigned-short block-ID field the current libMesh ExodusII_IO reader uses
  # ("restrict_int failed: <id> does not fit in type t"). base_final_50_blockid_fix.e is that
  # same mesh with its element-block IDs renumbered to fit (geometry, coordinates, connectivity,
  # and block/nodeset/sideset NAMES -- which is what this input and its Materials blocks
  # reference by name, not by numeric ID -- are unchanged by a renumbering).
  #
  # The original base_final_50.e is not present in this repository (on this branch or on
  # devel), so the renumbering is not independently auditable from git history alone. The
  # renumbered file's own embedded NetCDF metadata is the audit trail instead: its `title`
  # global attribute reads
  #   cubit(s/jinw-mac/projects/falcon/Applied_Energy/base_final_50.e): 10/02/2020: 22
  # (i.e. it was produced by Cubit from a file of that name), and its current eb_prop1/eb_names
  # (`ncdump -v eb_prop1,eb_names base_final_50_blockid_fix.e`) are:
  #   caps_HEX8=1, caps_WEDGE=3, aquifer_HEX8=2, aquifer_WEDGE=4
  # all comfortably within the unsigned-short range, consistent with a renumbering rather than a
  # from-scratch remesh.
