[Dune] dune-alugrid: Assertion `DetDf > 0' failed

[Jelena Grižić]

Dear all,


while constructing mesh from dgf file, I receive message :

dune-alugrid/dune/alugrid/3d/mappings_imp.cc:187: Dune::alu3d_ctype
Dune::TrilinearMapping::det(const coord_t&): Assertion `DetDf > 0' failed.

Could you explain what that exactly means and what could be problem with my
mesh?

Unfortunately, dgf file is to big (56,7 MB) to be included in mail.


Thank you.

Best regards,

Jelena Grižić
