Currently FVM is most popular method to solve fluid flow involving heat transfer problems and related physics. On the other hand, FEM is mostly suitable and popular for structural analysis.
Currently I have prepared a circuit which gives me constant current source of 10 micro ampere. 2 Volt DC source and 200 k Ohm resistor in series. What if the output volt of DC power supply...
