The boudnary segment index flag is the default except if it's
overwritten for a specfific grid. This is currently done in ALU which
per default only works with DGF boundary flags.

For gmsh we always want the intersection.boundarySegmentIndex as a
boundary flag, while for DGF file Alu grid needs to use the non-standard
intersection.impl().boundaryId().

* tiny changes in the PM velocity

Kilian Weishaupt authored Jul 02, 2019 and Kilian Weishaupt committed Jul 19, 2019

* not done for getParallelVelocityFromOtherBoundary -> will raise
  deprecation warning

* account for the tangential velocity gradient along the interface
* refactor some functions, add more docu

* introduce a new function for the slip velocity that also takes into account a later gradient
* introduce beta = alpha/sqrt(K)
* introduce a velocity in the porous medium (0 by default)

Throw if evalGradients is called with non-uniform phase states

Closes #624

See merge request !1670

Evaluating gradients inside an element is only correct if all
element vertices have the same phase state, i.e. the same set of
primary variables. Determine if all vertex phase states are the
same. If not, throw. Enable the possibility to ignore the phase
states and enforce the gradient evaluation.
