I have been trying to use compute group/group command for calculating the energy interaction between two adjacent groups of atoms, where one group is modeled using LJ and other group using EAM/fs. The interaction between the two groups is modeled with LJ.
I find the following error:
ERROR on proc 0: Invoked pair single on pair style none
 [MPI Abort by user] Aborting Program! "
However, when LJ is applied to all the groups, there is no error.
Any input on this problem would be of great help.
