WebAlways remember to check the FORCE_SETS file and verify that the displaced atoms are the ones with the largest forces acting on them, and that forces on other atoms are one or more orders lower; this can prevent your phonons from becoming imaginary. The forces can be adjusted by increasing (or lowering) the amplitude ( DISPLACEMENT_DISTANCE tag). WebSET = 560 V. All specifications T MIN to T MAX 2 unless otherwise noted.)
