◆ actions_before_newton_solve() [1/2]

template<class ELEMENT >
void SimpleShearProblem< ELEMENT >::actions_before_newton_solve ( )
inlinevirtual

Update before solve: We're dealing with a static problem so the nodal positions before the next solve merely serve as initial conditions. For meshes that are very strongly refined near the boundary, the update of the displacement boundary conditions (which only moves the SolidNodes on the boundary), can lead to strongly distorted meshes. This can cause the Newton method to fail --> the overall method is actually more robust if we use the nodal positions as determined by the Domain/MacroElement- based mesh update as initial guesses.

Reimplemented from oomph::Problem.
