It compiles and builds, but does not work yet. Requires OPM/IFEM#36. |

…field. Added: Option to return derivatives of the stress degradation function. Added: Parsing and printing of the stabilization parameter alpha, this is the same quantity as stabk in the CahnHilliard integrand.
Added: Penalty enforcement of crack irreversibility.
Changed: Move some common code into the new protected method getSolution.
- use self-written hermitian interpolator (GoTools is buggy) - find zeros of the derivative using a Newton loop instead of a (naive) line search
Added: Input of number of (uniform) points, or explicit point parameters, and tolerances for the line search. Added search from all grid points.
…search. Fixed: Sign of the derivative function f'(alpha). Added: Option to dump out f(alpha) and f'(alpha) to file.
Fixed: There was also an error in the calculation of f(alpha) itself (missing Gc-factor in front of the gradient term).
before checking convergence. Not sure if this will help though. Using L2-norm of the residual force vector for convergence check.
staggered solver, such that input files with initial condition setup for the monolithic version also can be used by the staggered solver without issues
