Problems with pair_style gran/hertz/history

Submitted by nikros on Thu, 12/17/2015 - 05:13

Hello, everyone.
I'm a new user of LIGGGHTS and now I'm trying to run tutorial and examples.

All the examples work fine, except of contactModels/in.oldModels.
The error is: ERROR: Invalid pair style (../force.cpp:244)
The online tutorial examples also give me an error:
ERROR: Invalid fix style: "wall/gran/hertz/history" (../modify.cpp:820)

I guess it is because in both cases the

pair_style gran/hertz/history

is used. And my LIGGHTS cannot recognise it.

Is my LIGGGHTS installed wrong way? Or I need instead of pair_style gran/hertz/history to use the

pair_style gran model hertz tangential history,

which is in the contactModels/in.newModels

Exactly, both refer to the same model, however, the former is the syntax of LIGGGHTS 2.x while the latter is the syntax of LIGGGHTS 3.x
