Hi, all,
I am trying to put atoms that meet a certain boolean condition to a group called "inwardatom". This is the code:
variable eatom2 atom "(v_DH>50e-6)&&(v_inOut<0)"
group inwardatom variable eatom2
The error message says:
ERROR: Illegal group command (group.cpp:341)
Can anyone tell me what causes it?
Thanks a lot!
