Does anyone use mbzoltan? I managed to build it but it dies: ~/> ./mbzoltan 32 input-s-gnep-fix.h5m y input-s-gnep-fix-z.h5m Using depricated construtor: MBCore::MBCore(rank,size) Segmentation fault From the error message I'm hoping that it might work with an older version of MOAB... Thanks, Alvaro
