- search_methodnearest_node_connected_sidesChoice of search algorithm. All options begin by finding the nearest node in the primary boundary to a query point in the secondary boundary.

This is fast to determine via a pregenerated node-to-elem map and is robust on conforming meshes. In the optional all_proximate_sides algorithm, primary boundary elements are searched iff they touch that nearest node, even if they are not topologically connected to it. This is more CPU-intensive but is necessary for robustness on any boundary surfaces which has disconnections (such as Flex IGA meshes) or non-conformity (such as hanging nodes in adaptively h-refined meshes).

# PorousFlow analogy of chemical_reactions/test/tests/solid_kinetics/2species_without_action.i
#
# Simple equilibrium reaction example to illustrate the use of PorousFlowAqueousPreDisChemistry
#
# In this example, two primary species a and b diffuse towards each other from
# opposite ends of a porous medium, reacting when they meet to form a mineral
# precipitate. The kinetic reaction is
#
# a + b = mineral
#
# where a and b are the primary species (reactants), and mineral is the precipitate.
# At the time of writing, the results of this test differ from chemical_reactions because
# in PorousFlow the mineral_concentration is measured in m^3 (precipitate) / m^3 (porous_material)
# in chemical_reactions the mineral_concentration is measured in m^3 (precipitate) / m^3 (fluid)
# ie, PorousFlow_mineral_concentration = porosity * chemical_reactions_mineral_concentration

# Two phase density-driven convection of dissolved CO2 in brine
#
# Initially, the model has a gas phase at the top with a saturation of 0.29
# (which corresponds to an initial value of zi = 0.2).
# Diffusion of the dissolved CO2
# component from the saturated liquid to the unsaturated liquid below reduces the
# amount of CO2 in the gas phase. As the density of the CO2-saturated brine is greater
# than the unsaturated brine, a gravitational instability arises and density-driven
# convection of CO2-rich fingers descend into the unsaturated brine.
#
# The instability is seeded by a random perturbation to the porosity field.
# Mesh adaptivity is used to refine the mesh as the fingers form.
#
# Note: this model is computationally expensive, so should be run with multiple cores,
# preferably on a cluster.
