If it matters, I am using UGGrid. Some version numbers: dumux 3.1,
dune-grid 2.6, dune-uggrid 2.6.

Hello,
I am a new DuMux user and I am trying to simulate a 2p2c flow on a 2D
rectangular area with one border being the influx and the opposite one
being the outflow (an the two others being walls, of course).
I used the example
dumux/test/porousmediumflow/2p/sequential/test_mpfa2p.cc as the
starting point of my program, using MPFA-L method.
All went fine on a regular grid. Now I am willing to try an
unstructured grid, too. From the docs, I figured that one recommended
way of creating unstructured grids is gmsh, am I correct?
.msh files obtained from gmsh 4 did not work because
Dune::IOError
[read:.../dune-grid/dune/grid/io/file/gmshreader.hh:297]: can only
read Gmsh version 2 files
Fair enough. I installed gmsh 3 and got past this error. Now I have
another one that I can not understand. The error message, with some
log before it, follows.
Reading parameters from file mpfa2p.input.
Reading 2d Gmsh grid...
version 2.2 Gmsh file detected
file contains 21574 nodes
file contains 43150 elements
number of real vertices = 21574
number of boundary elements = 500
number of elements = 42646
Initializing problem 'mpfal2p'
Dune reported error: Dune::NotImplemented
[storeInteractionVolumeInfo:.../dumux/dumux/porousmediumflow/2p/sequential/diffusion/mpfa/lmethod/2dpressure.hh:1156]:
fvmpfao2pfaboundpressure2p.hh, l. 1164: boundary shape not available
as interaction volume shape
So I thought that I am misusing gmsh and tried one of the
pre-installed .msh grids, namely
dune-grid/doc/grids/gmsh/curved2d.msh. I got the same error. So
probably I am misusing MPFA-L implementation and not gmsh. What should
I do to have an unstructured grid in this kind of simulation? Thank you.

Dmitry
