Incorporating disableNormalWhenBonded flag in model

Submitted by mschramm on Wed, 02/06/2019 - 15:56

Hello,
in the doc for the "gran model hertz model" there is the flag
disableNormalWhenBonded
How can I gain access to this?
When I tried adding it to an input script, I received the error
pair_style gran model hertz disableNormalWhenBonded on tangential history
ERROR on proc 0: Could not find bond history offset (../normal_model_hertz.h:134)

Thanks for all the help!
