the ones with i<=j.  The rest follows from symmetry of
the Hessian.

Needless to say, this makes the Hessian assembly quite
a bit faster.

Fix an index bug in evaluateFDDerivativeOfGradientWRTCoefficient · 29943ed7

Oliver Sander authored 13 years ago

This change makes the localgeodesicfefunction test fail again.
So there must be a bug in the corresponding non-finite-difference
code.  Looking at simplex cases confirms me in this opinion.
But I don't find the bug...

Start implementing the analytical gradient of the energy functional. · 775ba6e3

Oliver Sander authored 13 years ago

So far, the long form of the quadratic bending energy has been
implemented and tested, and it appears to do the right thing.

This is a snapshot commit.  The code remains out-commented until
it is finished.
