Source files description.

Source file	Description
main.cpp	Main simulation process is implemented in this file
electrics_calc.h, electrics_calc.cpp	All electric variables ($\mathrm{\Phi }$, $\mathit{E}$, $\sigma$, $\mathit{j}$, i, Q) are calculated in these files
temp_calc.h, temp_calc.cpp	Temperature transient solution is solved in these files
par.h	Biological, physical and numerical parameters are declared and/or initialized in this file
mesh.h, mesh.cpp	Mesh class keeps information about geometry and domain discretization. Instances of this class are used in the ScalarField class and VectorField class
scalar_field.h, scalar_field.cpp	ScalarField class is defined in these files. Instances of this class are used in main.cpp, electrics_calc.h, temp_calc.h for depicting $\mathrm{\Phi }$, $|\mathit{E}|$, $|\mathit{j}|$ and $\sigma$
vector_field.h, vector_field.cpp	VectorField class is defined in these files. Instances of this class are used in main.cpp, electrics_calc.h and temp_calc.h for depicting $\mathit{E}$ and $\mathit{j}$
save.h, save.cpp	Saving of the different scalar and vector fields as well as the log, are implemented in these files
