Detailed Description

Triangular element for Stokes flow using Bubble basis function. Linear+Bubble interpolation of velocity, and linear interpolation of pressures. The element is exported as a linear triangle (bubble dofs are not exported). It can deal with nonlinear material models, but it is assumed that the fluid is without memory (which is usually the case).
