Is the variations are all tangent to the manifold you don't actually need itremove the TargetSpace parameter of the Cosserat energy class -- Cosserat materials only make sense with RigidBodyMotion valuesIntroduce new class CosseratEnergyLocalStiffness.use only first-order quadrature ruleimplement the various derivatives of the squared distanceimplement method thirdDerivativeOfDistanceSquaredWRTSecondArgumentwrite output frame field into AmiraMesh filesreimplement evaluateFDDerivativeOfValueWRTCoefficient actually using the exponential mapdisable signalling on NaNallow to use structured and unstructured gridsmake the measuring code workminor documentation fixDocument how the Hessian fd approximation is computedBe smarter about when to compute what. This speeds up assembly of the Hessian for harmonic maps from R^3 to S^2 by a factor of 3move method assembleGradient out of the Imp class againfix index bugs. Test passes nowabort if there is a difference between the analytical Hessian and the fd Hessianbugfix: Hessian didn't have correct block sizealso test RealTuple<1>add a specialization for RealTuple<1>some refactoring to allow testing of other TargetSpacesmore fixesRemove class specializations. The old implementation for the UnitVector class will handle all casesremove obsolete method 'embeddedGradientOfEmbeddedGradient'Remove unnecessary multiplications with the orthonormal frame matricesfix index bugremove the field 'globalIsometricCoordinates'. It is not used after all.Remove a few specializations. From now on we will assume that all target spaces can be parametrized by some sort of global embedding. I don't see a case coming where that is not general enoughtest a few mixed derivatives as wellupdate list of files to be ignoredadd missing headerNew test for the fd approximation of the energy Hessianput each program on a separate linerename unitvectortest.cc to targetspacetest.ccbugfix in the measuring code: 1d-ness was hardwiredDo not use the word 'rods' in variable names. This code is not restricted to rods anymoreSolve the minimization problems for the evaluation of gfe functions really down to machine precision. This appears to make the overall algorithm much more stableshow assembly timings and the multigrid outputremove obsolete method assembleHessianApproximationremove lots of hardcoded 'double' data types
