Linearisation has many different meanings.. one is spectral methods, it is also used to linearize the system.
The others are numerical schemes like finite difference methods. Like forward, backward,
forward difference: U = [ U_(t+1) - U_t ] / dt
backward difference: U = [ U_t - U_(t-1) ] / dt
Basically, you try to model the higher order terms, derivatives etc with simple algebraic functions.
When you linearize then you get truncation errors and also an artificial viscosity term arises called CFL thanks to the numerical methods and this term has the effect of edge smoothing and determines the convergence or divergence of the problem based on step time. Because we want to reduce the computational time from orderOf(N^2) to N-log(N).

I need to go through my notices. BTW which text books are you following? and is it graduate or undergrad level course?

Dafa-ria her back....

Haha. No actually i am the one spreading the virus ....

Those are definitely to our east. Hands down. No contest.

On serious note* we are far better nation as compare to our humsaye in east.
We lacked a good leadership all these years

Dafa-ria ka virus baaji.. kia ho gya. 48 ki umar me satya gae ho kaa...

Btw shesha chelum jaisa hota ??

This is exactly what we are doing. This has been covered in the last lecture though.
Undergrad Level.
CFD by Hoffman.
CFD An Into By JD Anderson.

Hey can i get your email? I am thinking of taking up FYP in CFD, and i could always do with little help.

Oh I also followed JD Andersons during my undergrad. and then by Hirsch (a bit more advanced) at Masters.
okay I will give you my email

No this is very basic. The basic fundamentals are easy to grasp. All we do is to march in spatial and temporal domains...

Please tell me which part did you not understand in that, I can elaborate dobara phir se try

It’s not about understanding but how boring it is.
