- inputsThe input MeshGenerators.
C++ Type:std::vector<MeshGeneratorName>
Unit:(no unit assumed)
Controllable:No
Description:The input MeshGenerators.
MeshCollectionGenerator
Collects multiple meshes into a single (unconnected) mesh.
Overview
The MeshCollectionGenerator creates a new mesh that is a collection of sub-meshes (provided in the inputs parameter). The sub-meshes are not linked in any way and interaction between them only occurs due to contact or other constraints.
Input Parameters

## 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
# 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
# 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.
