How to get the type of the ElementContext?

[Markus Blatt]

I am going nuts!

I am adapting opm-simulators/opm/autodiff/StandardWellsDens*.hpp to get rid off the usage of cachedIntensiveQuantities which supposedly should not be used, see #163 . No I need to get the type of the ElementContext and I have no clue how to do this.

I tried to use code (which I do not like) like in BlackoilModelEbos:

// --------- Ebos property system stuff -------
typedef typename TTAG(EclFlowProblem) TypeTag;
typedef typename GET_PROP_TYPE(TypeTag, ElementContext)    ElementContext;

which yields the compile error:

/home/mblatt/src/dune/opm/opm-simulator/opm/autodiff/StandardWellsDense.hpp:78:35: error: ‘EclFlowProblem’ in namespace ‘Ewoms::Properties::TTag’ does not name a type
             typedef typename TTAG(EclFlowProblem) TypeTag;
                                   ^

Seems like this is defined in BlackoilModelEbos.hpp but including this header gives

/home/mblatt/src/dune/opm/opm-simulator/opm/autodiff/StandardWellsDense.hpp:78:35: error: ‘EclFlowProblem’ in namespace ‘Ewoms::Properties::TTag’ does not name a type
             typedef typename TTAG(EclFlowProblem) TypeTag;
                                   ^

You might have to also copy the top lines from BlackoilModelEbos, where EclFlowProblem is set.

Btw, I guess a look in the Dumux docu explains this.

Well that is what I tried.

The problem is that the header gets included multiple times. I might have figured it out now and will move the property definitions of BlackoilModelEbos to a separate header.

Thanks anyway.

I guess this can be closed.

I have the similar problem now.

In small test file, I included the header files

 35 #include <ebos/eclproblem.hh>
 36 #include <ewoms/common/start.hh>

But when I tried

 using TypeTag = typename TTAG(EclFlowProblem);

I got the error

error: ‘EclFlowProblem’ in namespace ‘Ewoms::Properties::TTag’ does not name a type

I found it. It is introduced in BlackoilModelEbos.hpp.
