[aspect-devel] cannot allocate an object of abstract type ‘aspect::MaterialModel::Simpler<3>’

[Lev Karatun]

Hi Rene,

my interface.h and interface.cc were indeed messed up, I must have resolved
a conflict wrong at some point. Anyway, it all works now, thanks for
helping!

Best regards,
Lev Karatun.
