Crank Nicholson -- CFD Online Discussion Forums

noName Guest Posts: n/a	Hi -- Could someone tell me what the exact disadvantages of Crank Nicholson scheme are (when used to solve the Navier Stokes Equations)? I know that there exists a CFL condition when stability is analyzed in the max norm, but there is no restriction when analyzed in the 2-norm. I also know that for more than 1-D Crank Nicholson may be too expensive to invert (hence the use of ADI, etc). What do you think are the main reasons that people prefer not to use Crank Nicholson (or, maybe, prefer to use it)?
