FDM for Computational Finance

[Zhirun]

I am a fresh graduate in Financial Engineering.
I hear PDE plus FDM is useful for option pricing(BS PDE model) in reality. Is it how people do in the industry?
And constructing the system is usually the quantitative developer's job?

PDE/FDM is useful for mostly 1 and 2 (maybe 3) factor models (pricing and calibration) For n-factor you need some form of simulation, for example Monte Carlo. And combined MC/PDE models are possible.
FDM's strong points are efficiency and predictable output.

Some universities have it as a requirement.
