What is the difference between edge finite elements and nodal finite elements?
This for use in modeling the eddy current problem in classical electromagnetism. I am attempting to convert MATLAB code written for Electrical Impedance Tomography (EIT) into a code for Magnetic Induction Tomography (MIT). EIT involves electrodes with applied alternating currents and requires nodal FEM. Whereas MIT involves coils and induction of eddy currents and requires edge FEM.
The code for both EIT and MIT involves solving the forward and inverse problems in a simulation for tomographic image reconstruction of conductivity maps.
The MATLAB code for conversion is found at EIDORS:
