Solving PDE’s with electrical circuit analogy

One of our group member has successfully defended his Ph.D.. His thesis was on "Solution of Network Coupled Partial Differential Equations Through Electrical Analogy".  Abstract of his thesis : In the thesis, Partial Differential Equations (PDEs) are modeled by an electrical circuit generated from the equations arising from the Finite Element Method. This allows the …
