Use fix property/atom data ini other fix

Dear all,

Can anyone of you please help me how to use an added property of per atom, that is added by fix property/atom?

I am going through the src file of fix property/atom and fix langevin - (where i have planned to implement it during force calculation) repeatedly but cannot make out how to use the added per/atom data extracted by fix property/atom.

Thanks,

please use the method find_custom() in the Atom class. it will return
an index and set a flag whether the named custom property is an
integer or double.
then you can use this index as the first dimension in when accessing
the ivector or dvector 2d-arrays, respectively, where the data is
stored.

if you look through the source code, you will find plenty of examples
where such custom properties are accessed.
