for finite element methods, the geometry is cut into meshes and you do piecewise approximation on each mesh.
for finite volume methods, approximations are done on the volume around node.
a hint for V: when you have 2+ independent sources, consider superposition.
also, you don't have 5 equations with 8 unknowns. Is, Vs are given. a and b is what eventually you are looking for, in terms of the other variables.
try it again, and you should have just the right amount of equations...
hi guys, i came across this problem in my material science class.
can anyone help me with this problem?
thanks!
** (-> an electron)
Ec ___________________________ }-> 0.2eV, from Ec to electron Ec - Ev = 1eV
