In the EQS folders there are the solvers. 

EQS_....C: is the main file. It contains the power method, all the commands necessary for the solution and amplitude evaluation

Geometrical_study.H: it studies the mesh of system 

Make_mesh.H: it changes the mesh automatically or by input 

operators.H: it evaluates some particular quantities with differential operators

createFields_fi.H: it declares the flux and the properties 

createFields.H: it declares the amplitudes and the coefficients 

Weights.H: it evaluates the coefficients 

Weights_delayed.H: it evaluates the coefficients in case of delayed insertion
