[FLASH-USERS] meshCopyCount and Hyper

Hi,

When using meshCopyCount >1 both in UG and AMR, my simulation crashed at time step 1.
My current hypothesis is that it is linked to the Hyper version I’m using, Hyper 2.19, which is more recent than what is advised in the FLASH4.8 documentation. 
The simulations with meshCopyCount = 1 run normally.

Could anyone using FLASH4.8 with multi-group radiative transport check if the simulations are running normally when putting meshCopyCount = 2 or above? I want to be sure it’s a problem with the Hyper library and not an incompatible option (legacy) for FLASH4.8

Thanks in advance,
Best regards,
Gabriel
