[Dune] a problem with refinement

[arya fallahi]

Dear Dune support team,

I have a problem with refining a very simple grid, introduced by a dgf file. When I try to a refinement using  " alusimplexgrid->globalRefine(1); " The code crashes and returns the following message:

Assertion failed: (fabs( quadraturTetra3D < VolumeCalc > ( LinearMapping ( this->myvertex(0)->Point(), this->myvertex(1)->Point(), this->myvertex(2)->Point(), this->myvertex(3)->Point())).integrate1 (0.0) - _volume ) < 1e-10), function TetraTop, file serial/gitter_tetra_top.h, line 1114.

Since, the file is a ver simple 12 tetrahedra grid and I can not find any errors in it, I think it may be a problem with dune. I will be thankful if you have a look at the problem and let me know what is mainly the source of error.
