Model Order Reduction (MOR)

To download the baffle case snapshots, go to MOR/bin and run ./gsnaps baf. To download the cyl case snapshots, go to MOR/bin and run ./gsnaps cyl.

For each case run ../../bin/linkc in a case directory to link the source.

Lid-Driven Cavity

A 2D case used to reproduce [1].

Domain: x,y \in [-1,1] BCs: u(x,y) = \delta (y-1) * (1-x^2)^2

The top boundary condition is not the standard uniform velocity for consistency with [1]
