C++ Type:UserObjectName
Controllable:No
Description:The UserObject that holds the list of PorousFlow variable names.
PorousFlowHeatEnergy
Calculates the sum of heat energy of fluid phase(s) and/or the porous skeleton in a region
This Postprocessor calculates the heat energy of fluid phase(s) using where all variables are defined in nomenclature.
The phases that the heat energy is summed over can be entered in the phase input parameter. Multiple indices can be entered.
By default, the additional heat energy due to the porous material is added to the heat energy of the fluid phase(s). This contribution can be ignored by setting include_porous_skeleton = false.
The flag use_displaced_mesh = false is set internally by this Postprocessor, and the parameter cannot be altered by the user, even for simulations with solid-mechanical deformation. The reason is that this postprocessor uses the strain calculated by TensorMechanics to automatically compensate for deformed meshes. Further information may be found here. Therefore:
For mechanically-coupled simulations, you must provide a
base_namethat is identical to that used by the TensorMechanics strain calculator, so that this Postprocessor can retrieve the correct strain. The most common use-case is that you provide nobase_nameto the TensorMechanics strain calculator and hence nobase_nameto this Postprocessor.For non-mechanically-coupled simulations, you must not provde a
base_namethat is used in any TensorMechanics strain calculators. The most common use-case is that you have no TensorMechanics strain calculators, so you needn't worry about providing anybase_nameto this postprocessor. However, there is a possibility that you have a TensorMechanics strain calculator but you don't want to couple mechanics to PorousFlow. In that case, supplybase_name = non_existent, or similar, so that this Postprocessor doesn't retrieve any strain.
Input Parameters
- base_nameFor non-mechanically-coupled systems with no TensorMechanics strain calculators, base_name need not be set.

# heat04, but using an action
#
# The sample is a single unit element, with fixed displacements on
# all sides. A heat source of strength S (J/m^3/s) is applied into
# the element. There is no fluid flow or heat flow. The rise
# in temperature, porepressure and stress, and the change in porosity is
# matched with theory.
#
# In this case, fluid mass must be conserved, and there is no
# volumetric strain, so
# porosity * fluid_density = constant
# Also, the energy-density in the rock-fluid system increases with S:
# d/dt [(1 - porosity) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T] = S
# Also, the porosity evolves according to THM as
# porosity = biot + (porosity0 - biot) * exp( (biot - 1) * P / fluid_bulk + rock_thermal_exp * T)
# Finally, the effective stress must be exactly zero (as there is
# no strain).
#
# Let us assume that
# fluid_density = dens0 * exp(P / fluid_bulk - fluid_thermal_exp * T)
# Then the conservation of fluid mass means
# porosity = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T)
# where dens0 * por0 = the initial fluid mass.
# The last expression for porosity, combined with the THM one,
# and assuming that biot = 1 for simplicity, gives
# porosity = 1 + (porosity0 - 1) * exp(rock_thermal_exp * T) = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T) .... (A)
#
# This stuff may be substituted into the heat energy-density equation:
# S = d/dt [(1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T]
#
# If S is constant then
# S * t = (1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T
# with T(t=0) = 0 then Eqn(A) implies that por0 = porosity0 and
# P / fluid_bulk = fluid_thermal_exp * T - log(1 + (por0 - 1) * exp(rock_thermal_exp * T)) + log(por0)
#
# Parameters:
# A = 2
# fluid_bulk = 2.0
# dens0 = 3.0
# fluid_thermal_exp = 0.5
# fluid_heat_cap = 2
# por0 = 0.5
# rock_thermal_exp = 0.25
# rock_density = 5
# rock_heat_capacity = 0.2

# The sample is a single unit element, with fixed displacements on
# all sides. A heat source of strength S (J/m^3/s) is applied into
# the element. There is no fluid flow or heat flow. The rise
# in temperature, porepressure and stress, and the change in porosity is
# matched with theory.
#
# In this case, fluid mass must be conserved, and there is no
# volumetric strain, so
# porosity * fluid_density = constant
# Also, the energy-density in the rock-fluid system increases with S:
# d/dt [(1 - porosity) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T] = S
# Also, the porosity evolves according to THM as
# porosity = biot + (porosity0 - biot) * exp( (biot - 1) * P / fluid_bulk + rock_thermal_exp * T)
# Finally, the effective stress must be exactly zero (as there is
# no strain).
#
# Let us assume that
# fluid_density = dens0 * exp(P / fluid_bulk - fluid_thermal_exp * T)
# Then the conservation of fluid mass means
# porosity = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T)
# where dens0 * por0 = the initial fluid mass.
# The last expression for porosity, combined with the THM one,
# and assuming that biot = 1 for simplicity, gives
# porosity = 1 + (porosity0 - 1) * exp(rock_thermal_exp * T) = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T) .... (A)
#
# This stuff may be substituted into the heat energy-density equation:
# S = d/dt [(1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T]
#
# If S is constant then
# S * t = (1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T
# with T(t=0) = 0 then Eqn(A) implies that por0 = porosity0 and
# P / fluid_bulk = fluid_thermal_exp * T - log(1 + (por0 - 1) * exp(rock_thermal_exp * T)) + log(por0)
#
# Parameters:
# A = 2
# fluid_bulk = 2.0
# dens0 = 3.0
# fluid_thermal_exp = 0.5
# fluid_heat_cap = 2
# por0 = 0.5
# rock_thermal_exp = 0.25

# Since fluid_mass is conserved, and volume = (1 - 0.01*t), this can be solved for temperature:

(modules/porous_flow/test/tests/energy_conservation/heat04_fullysat_action.i)
# heat04, but using an action
#
# The sample is a single unit element, with fixed displacements on
# all sides. A heat source of strength S (J/m^3/s) is applied into
# the element. There is no fluid flow or heat flow. The rise
# in temperature, porepressure and stress, and the change in porosity is
# matched with theory.
#
# In this case, fluid mass must be conserved, and there is no
# volumetric strain, so
# porosity * fluid_density = constant
# Also, the energy-density in the rock-fluid system increases with S:
# d/dt [(1 - porosity) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T] = S
# Also, the porosity evolves according to THM as
# porosity = biot + (porosity0 - biot) * exp( (biot - 1) * P / fluid_bulk + rock_thermal_exp * T)
# Finally, the effective stress must be exactly zero (as there is
# no strain).
#
# Let us assume that
# fluid_density = dens0 * exp(P / fluid_bulk - fluid_thermal_exp * T)
# Then the conservation of fluid mass means
# porosity = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T)
# where dens0 * por0 = the initial fluid mass.
# The last expression for porosity, combined with the THM one,
# and assuming that biot = 1 for simplicity, gives
# porosity = 1 + (porosity0 - 1) * exp(rock_thermal_exp * T) = por0 * exp(- P / fluid_bulk + fluid_thermal_exp * T) .... (A)
#
# This stuff may be substituted into the heat energy-density equation:
# S = d/dt [(1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T]
#
# If S is constant then
# S * t = (1 - porosity0) * exp(rock_thermal_exp * T) * rock_density * rock_heat_cap * T + porosity * fluid_density * fluid_heat_cap * T
# with T(t=0) = 0 then Eqn(A) implies that por0 = porosity0 and
# P / fluid_bulk = fluid_thermal_exp * T - log(1 + (por0 - 1) * exp(rock_thermal_exp * T)) + log(por0)
#
# Parameters:
# A = 2
# fluid_bulk = 2.0
# dens0 = 3.0
# fluid_thermal_exp = 0.5
# fluid_heat_cap = 2
# por0 = 0.5
