P2P1 triangles were used to discretize the Stokes Equations.
Lid Driven Cavity
The velocity magnitude and vectors for the Lid Driven Cavity problem. The top wall has a fixed velocity of 1 and the sides and bottom have no slip boundary conditions.
Flow Over a Cylinder
The velocity magnitude, vectors, and streamlines for Stokes Flow across a cylinder.
The code can be found here. Building the stokes.cpp executable and running:
./stokes.exe cavity
and
./stokes.exe flow
will generate the data for the plots shown above.
