Vortex Dynamics -- Finite area vortices

These models find the motion of one or more patches of uniform vorticity.

Initial conditions:

Specify the initial positions, shapes, and strengths of the vortices as comma-separated lists

Initial center x positions:

Initial center y positions:

Initial radii (in the area average sense):

Initial semiaxis in x direction:

Vorticity in patch:

Shear:

You can also include a background shear flow U = s*y.

Shear:

Deformation radius:

You can also include a vortex stretching term with gamma = 1/Rd.
