Fluka 2020 model

Hi,
can anyone send the fluka 2020 version? I want to use Corsica flukacern model for my simulation and it seems that the new versions are not compatible.
Thanks

That one is not a version distributed by CERN, who - together with collaborating institutes - maintain and develop FLUKA as distributed from https://fluka.cern.
You may want to inquire with CORSIKA developers about the compatibility loss.
