ModularGapConductanceConstraint
Computes the residual and Jacobian contributions for the 'Lagrange Multiplier' implementation of the thermal contact problem. For more information, see the detailed description here: http://tinyurl.com/gmmhbe9
The ModularGapConductanceConstraint class is used specify a heat flux across a gap. The flux is computed by user objects derived from GapFluxModelBase. Such as
Multiple models can be specified with their contributions getting summed up.
Gap geometry types
Plate, cylindrical, and spherical gap geometries can be specified using the "gap_geometry_type" parameter.
For cylindrical geometries, e.g. gap_geometry_type = cylinder, the axis of the cylinder can be specified using the "cylinder_axis_point_1" and "cylinder_axis_point_2" parameters. In 2D Cartesian coordinate systems (e.g. Mesh/coord_type=XYZ), these parameters can be omitted to automatically determine the cylinder axis. This is accomplished by averaging positions over the primary side set, which should yield the center of the cylinder, assuming the side set spans the entire 360 degree rotation around the theoretical axis. The axis is then extended in z-direction.
For spherical geometries the origin of the sphere can be specified using the "sphere_origin" parameter. If the parameter is omitted, the sphere origin is deduced by averaging positions over the primary side set.
commentnote
If the gap is sliced by a symmetry plane (e.g. only a quarter of a cylinder or an eighth of a sphere are modeled), the positional average over the primary side set will not yield the correct origin or axis and they will need to be supplied manually.

## Units in the input file: m-Pa-s-K
# The analytical solution for a steady state thermal contact and a mechanical
# contact pressure of 1Pa, the temperature of the steel block at the interface
# is calcaluated as
#
# T^s_{int} = \frac{T^a_{BC}C_T k_a + T^s_{BC} k_s \left(k_a +C_T \right)}{k_s (k_a + C_T) + k_a C_T}
# T^s_{int} = 460K
#
# with the boundary conditions and thermal conductivity values specified in the
# input file below. Similarly, the temperature of the aluminum block (cold block)
# is calculated as
#
# T^a_{int} = \frac{T^s_{int} C_T + T^a_{BC} k_a}{k_a + C_T}
# T^a_{int} = 276K
#
# The values predicted by the simulation at the interface converge towards these
# temperature values, and are within a few degrees by 240s. A smaller timestep
# than is practical for the regression test application further reduces the difference
# between the analytical solution and the simulation result.

## Units in the input file: m-Pa-s-K-V
# In this steady-state, symmetric simulation, the temperature at the interface between
# the two blocks of aluminum can be calculated through Fourier's law (see the documentation
# page for ADInterfaceJouleHeatingConstraint for the relevant formulas).
#
# With the prescribed 0.0 V (left) and 0.3V (right) potential boundary conditions, the
# electric potential drop is 9.25e6 [V * S / m^2]. From this current-density-like LM variable,
# the volumetric heat source at the interface is calculated as
# q = 1.15625e6 [W/m^3}
# Because of the 2D nature of this problem, the volumetric heat source is equal to
# the negative of the heat flux at the interface.
#
# Finally, the temperature at the interface is computed as a function of the block width,
# thermal conductivity, and specified temperature boundary condition (300K on both the
# left and right edges):
# T_{interface} = 850.5952K
# which matches the simulation result to the 6 decimal places shown.

## Units in the input file: m-Pa-s-K-V
# Using the steady-state Fourier's law, the temperature at the interface in each block,
# in the case where thermal contact between the two blocks at the interface is not
# considered, (steel block on left, aluminum on right) is calculated as:
#
# T_{interface - steel} = 816.849K
# T_{interface - aluminum} = 339.871K
# which matches the simulation results to the 6 decimal places shown.
# As expected, the heat flux resulting from the volumetric Joule heating source is
# equivalent on both sides of the interface.
