Dear LAMMPS users,

I tried to run the example 'thermodynamic integration' by user Freitas. I used a LAMMPS version from March and a serial executable. LAMMPS does not recognize the style. You can see my run command and the ouput below. I can not figure out why. Can someone give any idea? Do I need to compile any additional package (which?)?

​you have to install the USER-MISC package. i see, that the fix ti/spring documentation does not state this. it will be updated accordingly in the next LAMMPS patch.

Thanks in advance,

Pedro Moreira
