# This input file is used to test that the interior axial boundaries of a
# heat structure are being created correctly.
#
# To test this, an arbitrary temperature distribution is imposed on the heat
# structure, and the average temperature on the interior axial boundaries is
# tested against expected values.
#
# The interior axial boundaries are located at x={20,40}, and radial boundaries
# are located at y={0,0.5,1,1.5}. The temperature is set to be T(x,y) = xy. The
# following table gives the resulting expected average temperature values on

# Tests that energy conservation is satisfied in 1-phase flow when there are
# multiple heat structures are connected to the same pipe.
#
# This problem has 2 heat structures with different material properties and
# initial conditions connected to the same flow channel, which has solid wall
# boundary conditions at both ends. An ideal gas equation of state is used for
# the fluid:
# e(T) = cv * T
# From energy conservation, an analytic expression for the steady-state
# temperature results:
# (rho(p,T)*e(T)*V)_fluid + (rho*cp*T*V)_hs1 + (rho*cp*T*V)_hs2 = constant
# The following are constant:
# V_i domain volumes for flow channel and heat structures
# rho_fluid fluid density (due to conservation of mass)
# rho_hsi heat structure densities
# cp_hsi heat structure specific heats
# Furthermore, all volumes are set equal to 1. Therefore the expression for the
# steady-state temperature is the following:
# T = E0 / C0
# where
# E0 = (rho(p0,T0)*e(T0))_fluid + (rho*cp*T0)_hs1 + (rho*cp*T0)_hs2
# C0 = (rho(p0,T0)*cv)_fluid + (rho*cp)_hs1 + (rho*cp)_hs2
#
# An ideal gas is defined by (gamma, R), and the relation between R and cv is as
# follows:
# cp = gamma * R / (gamma - 1)
# cv = cp / gamma = R / (gamma - 1)
# For the EOS parameters
# gamma = 1.0001
# R = 100 J/kg-K
# the relevant specific heat is
# cv = 1e6 J/kg-K
#
# For the initial conditions
# p = 100 kPa
# T = 300 K
# the density and specific internal energy should be
# rho = 3.3333333333333 kg/m^3
# e = 300000000 J/kg
#
# The following heat structure parameters are used:
# T0_hs1 = 290 K T0_hs2 = 310 K
# rho_hs1 = 8000 kg/m^3 rho_hs2 = 6000 kg/m^3
# cp_hs1 = 500 J/kg-K cp_hs2 = 600 J/kg-K
#
# E0 = 1e9 + 8000 * 500 * 290 + 6000 * 600 * 310
# = 3276000000 J
# C0 = 3.3333333333333e6 + 8000 * 500 + 6000 * 600
# = 10933333.3333333 J/K
# T = E0 / C0
# = 3276000000 / 10933333.3333333

# The temperature distribution is the following linear function:

# The integral of this function w.r.t. y = (y2, y3) is

# This test tests the loop identification function, which creates a map of component
# names to a loop name. "Loops" are defined to be sets of components which are
# physically connected - heat exchanger connections do not constitute physical
# connections in this sense. Note that this test is not meant to actually perform
# any physical computations, so dummy values are provided for the required parameters.
#
# The test configuration for this test is the following:
#
# pipe1 -> corechannel:pipe -> pipe2 -> hx:primary -> pipe1
# j1 j2 j3 j4
#
# inlet -> hx:secondary -> outlet
#
# This test uses the command-line option "--print-component-loops" to print out
# the lists of components in each loop, with the desired output being the
# following:
#
# Loop 1:
#
# corechannel:pipe
# hx:primary
# j1
# j2
# j3
# j4
# pipe1
# pipe2
#
# Loop 2:

# hx:secondary
# inlet
