OptimizedHeatSolver Module

Produces the libnuma-eheatsolver.so module. This is a refactoring of the upstream HeatSolver module into separate much more manageable routines. It also adds support for cell-death dependent parameters.

HeatSolve

Only differences from the upstream HeatSolve are documented here. The cell death extensions include new parameters for coagulation (cell-death based power deposition adjustment) and vapourization (temperature-based power deposition adjustment). Perfusion rate is also variable based on a cell-death status. Can output a Heat Source variable that shows the profile going into the Pennes equation.

Code improvements include splitting routines between files to ensure namespacing, proper declarations for routines, ensuring only used variables are allocated, consistent capitalization, ensuring only used variables are declared.

TODO: this code included initial work on assembling only cells that had changed (e.g. cell-death status). This needs to be finished.

Parameter	Location	Type	Default	Description
Coagulation Cut Off	Solver	Real	-	Level over which cell-death value indicates no local heating
Coagulation Gradient	Solver	Real	-	Slope backward from cell-death cut off as a coefficient for local heating (slope stops when it hits x1)
Coagulation Minimum Deposition	Solver	Real	-	Level below which cell-death-based coefficient cannot drop
Vapourization Cut Off	Solver	Real	-	Level over which temperature value indicates no local heating
Vapourization Gradient	Solver	Real	-	Slope backward from temperature cut off as a coefficient for local heating (slope stops when it hits x1)
Vapourization Minimum Deposition	Solver	Real	-	Level below which temperature-based coefficient cannot drop
Dead Threshold	Solver	Real	0.8	Value above which a cell is considered dead. This is separate from coagulation and vapourization.
Death Perfusion Rate	Solver	Real	0.0	Perfusion rate for cells identified as dead
Death Heat Capacity	Solver	Real	670.0	Heat capacity for cells identified as dead
Heat Source Visualization	Solver	Logical	FALSE	Calculate a Heat Source variable showing the final, combined heating
