Example 5513: Inflation of a trilinear prolate element of incomp + fluid shift pole-zero material

Finite elasticity analysis: 2kPa inflation of a prolate element with rotating fibre and sheet fields and an incompressible + fluid shift pole-zero material law. Geometry is interpolated isochorically (Focus^3.Cosh[lambda].Sinh^2[lambda]).Hydrostatic pressure varies quartically in the transmural direction. Uses Newton's method with GMRES to solve the sparsely stored linear equations.
