C++# This section documents the C++ implementation of the MOLE toolkit. Overview# The C++ implementation provides high-performance operators and boundary conditions for numerical computations, with a focus on mimetic methods. Class Structure# The following diagram shows the key classes in the MOLE C++ API and their relationships: digraph mole_class_structure { bgcolor="transparent"; rankdir=TB; // Top to Bottom layout compound=true; node [shape=box, style=filled, fontname="Arial", fontsize=10, margin="0.3,0.1"]; edge [fontname="Arial", fontsize=9]; // Color definitions node [fillcolor="#E8F4F9"]; // Light blue for base nodes // Core base classes subgraph cluster_base { label="Base Classes"; style=filled; color="#F5F5F5"; sp_mat [label="sp_mat\n(Armadillo)"]; Operator [label="Operator\n(Abstract Base)"]; } // Operators subgraph cluster_operators { label="Core Operators"; style=filled; color="#F5F5F5"; node [fillcolor="#D5E8D4"]; // Light green for operators Interpol [label="Interpol\n(Interpolation)"]; Gradient [label="Gradient"]; Divergence [label="Divergence"]; Laplacian [label="Laplacian"]; } // Boundary Conditions subgraph cluster_bc { label="Boundary Conditions"; style=filled; color="#F5F5F5"; node [fillcolor="#FFE6CC"]; // Light orange for boundary conditions RobinBC [label="RobinBC\n(Robin/Neumann/Dirichlet)"]; MixedBC [label="MixedBC\n(Mixed)"]; } // Utility Components subgraph cluster_utils { label="Utilities"; style=filled; color="#F5F5F5"; node [fillcolor="#DAE8FC"]; // Light blue for utilities Utils [label="Utils\n(Helper Functions)"]; GridFunctions [label="Grid Functions"]; WeightFunctions [label="Weight Functions"]; } // Inheritance relationships edge [color="#0000AA", penwidth=1.5]; sp_mat -> Operator [dir=back, arrowtail=empty]; Operator -> {Interpol Gradient Divergence Laplacian RobinBC MixedBC} [dir=back, arrowtail=empty]; // Usage relationships edge [style=dashed, dir=forward, color="#006600", penwidth=1.0]; Gradient -> Laplacian; Divergence -> Laplacian; // Utility relationships edge [style=dotted, dir=forward, color="#990000", penwidth=1.0]; Utils -> {Gradient Divergence Laplacian}; Utils -> {RobinBC MixedBC}; GridFunctions -> {Gradient Divergence}; WeightFunctions -> {Interpol Gradient Divergence}; // Boundary condition relationships edge [style=dashed, constraint=false, color="#AA6600", penwidth=1.0]; RobinBC -> {Gradient Divergence}; MixedBC -> {Gradient Divergence}; // Add a legend subgraph cluster_legend { label="Legend"; style=filled; color="#F5F5F5"; fontsize=10; node [shape=none, style=none, label=""]; edge [style=none]; leg_title [label="Relationship Types:", shape=none, fontsize=9]; leg_inherit [label="Inheritance", shape=none, fontsize=9]; leg_usage [label="Usage", shape=none, fontsize=9]; leg_utility [label="Utility Support", shape=none, fontsize=9]; leg_boundary [label="Boundary Modification", shape=none, fontsize=9]; leg_title -> leg_inherit [style=solid, color="#0000AA", penwidth=1.5]; leg_title -> leg_usage [style=dashed, color="#006600", penwidth=1.0]; leg_title -> leg_utility [style=dotted, color="#990000", penwidth=1.0]; leg_title -> leg_boundary [style=dashed, color="#AA6600", penwidth=1.0]; } } Advanced Usage For advanced usage patterns and performance optimization, check out the individual class documentation pages.
