Hi,
I’m a senior student in the University of Science and Technology Beijing. I major in thermal science and energy engineering. I’m using lammps to simulate the thermal properties of COFs.Now I need to use improper_harmonic. However, it is said “This improper style can only be used if LAMMPS was built with the MOLECULAR package (which it is by default).” And t saw your reply about this question. So I modify "MOLECULAR " to “MOLECULE” in the improper_harmonic.txt manually. But after I rebuilt LAMMPS and run my program, it still tell me “invalid improper style”. How can I successfully use this improper style?
Expecting your good solution!
