toms866


toms866, an Octave code which embodies version 2.2 of the Incompressible Flow Iterative Solution Software (IFISS), that can model the steady (time-independent) flow of a 2D incompressible fluid, by Howard Elman, Alison Ramage, David Silvester.

The library includes algorithms for discretization by mixed finite element methods and for a posteriori error estimation of the computed solution.

The most recent version of the software may be found by going to https://www.maths.manchester.ac.uk/~djs/ifiss/

The text of many ACM TOMS algorithms is available online through ACM: https://calgo.acm.org/ or NETLIB: https://www.netlib.org/toms/index.html.

The four classes of problems that can be solved by this code are identified by an alphabetic code:

There are four predefined example problems for the Poisson or diffusion equation:

There are four predefined example problems for the convection/diffusion equation. All problems are posed on a square domain with a convective velocity of order 1:

The four predefined Stokes problems:

The four predefined Navier-Stokes problems:
