Re: [ff3d-users] Navier Stokes

[Stephane Del Pino]

Hello.

Here is an example of none projection algorithm: the complete coupled system 
is built.

This example is written using the variational formula description, it could 
also be built using PDEs. If you are interested in the translation, I can do 
it.

Quantities are initialized by a simple Stokes computation.

Linear systems are solved using bi-conjugate gradient, this is a weakness of 
this approach, no efficient preconditioner for this is implemented in ff3d. 
Another disadvantage compared to projection methods is the use of memory: a 
global system is built instead of 4 smaller.

Best regards,
Stephane.
