this is required for regex-matching keywords. Once GCC 4.9 is the
minimum compiler version to be supported, this can be dropped in favor
of std::regex ...
dynamical parameter given in the parameter file. The default is 0 (as before).
In addition the relaxation parameter has been added to the parameter with the
default preserving the state from before.
Also, the default parameter for use_amg and use_bicgstab in the constructor of
CPRPrecondition have been removed.
Note that this patch does not introduce any real temperature
dependence but only changes the APIs for the viscosity and for the
density related methods. Note that I also don't like the fact that
this requires so many changes to so many files, but with the current
design of the property classes I cannot see a way to avoid this...
GCC 4.8 provides 'nullptr' in C++11 mode. That capability is
detected at configuration time and stored in <config.h> and we need
it when targeting Dune 2.2.1 to avoid diagnostics of the form
[...]/dune/common/nullptr.hh:27:1:
error: expected ‘;’ after class definition
} nullptr = {}; // and whose name is nullptr
^
[...]/dune/common/nullptr.hh:27:1:

[...]/dune/common/nullptr.hh:27:3:

This restores the performance to approximately the level it had before
the change to support non-diagonal well jacobians, for SPE9. All changes
are to the eliminateVariable() method.
- Explicitly compute and apply the inverse.
- Change loop ordering to apply inverse only num_eq - 1 times, instead
of (numeq - 1)^2.
- Use UmfPackLU instead of SparseLU.
1. The right hand side is solved only once
2. The solver is constructed directly with the matrix
3. const is added where it was missing
4. More commennts is added
5. Variable names are changed for clarification
The following comments has been adressed
1. An array is used in stead of pair
2. is not empty is used instead of size>0 to check if the well has been
initialized before
3. const_iterator is used instead of iterator
4. partial copy is removed
5. WellMapType is no longer mutable
If we need more than 150 linear iterations, it's probably something
wrong, and we may be better of by restarting with smaller time-steps.
TODO: make it possible for the user to specify this number.
The non-diagonal elements in the sub-matrices in the Schur complement is
no longer ignored. Instead of assuming the matrix do be diagonal, and
compute the invert of the sub-matrix, small linear systems are solved
using superLU.
Tested on SPE3 and Norne. (With this fix a slightly modified norne runs
until 3292 days)
The residual output is changed from max residual to
total mass balance residual. In this way the output
resemble what is actually used as convergence criteria.
With the introduction of shut wells the same ordering in the well states
can no longer be assumed. The well names is instead used to map the old
well state to the new. Also the partial_copying is moved into the
initialization.
Tested on SPE1, SPE3, SPE9 and Norne. (Do not change the SPEs and is
nessesary for the Norne)
