The geometric approach to hydrodynamics was developed by Arnold
to study Lagrangian stability of ideal fluids. It identifies a
Lagrangian fluid flow with a geodesic on the Riemannian
manifold of volume-preserving diffeomorphisms. The curvature of
this manifold is typically negative but sometimes positive, and
positivity leads to conjugate points (where initially close
geodesics spread apart and come together again).

We shall discuss a multiscale modeling and simulation formalism for soft matter materials taking into account hydrodynamic interactions and thermal fluctuations. A specific motivation is the study of lipid bilayer membranes and polymer fluids taking into account microstructure degrees of freedom. The approach is based on the immersed boundary method, where hydrodynamic interactions of the composite system are handled by an approximate treatment of the fluid-structure stresses.

We present a family of dipole models for describing the far-field hydrodynamic interactions in populations of self-propelled bodies. Interestingly, but perhaps not surprisingly, the dipolar far-field effect is descriptive of swimming bodies (e.g., fish) at high Re numbers as well as self-propelled particles (e.g., bacteria) in confined geometries such as in Hele-Shaw cells. We argue that our models can be used in both contexts, that is, fish schooling and confined motile micro-particles.
