thanks a lot for your response,
I actually used HOMEBREW to install LAMMPS and the associated packages and it has been working fine for other systems ( without hybrid/overlay ).
So based on your feedback the issue could be from the substyles installation, so do to get over this issue ?
I have been working calcite/water system by using a published force field, I
am getting an error at some point shown below. I am pretty sure about my
executables and packages installed are fine. I am suspecting the issue is
with the pair_style hybrid/overlay because I have never used this style
before, and related more or less to the below part of the force field file.
Kindly check below the error and part of the force field…
please check whether your executable has all the various pair
the parser logic of the pair_style hybrid line is that all “words”,
that are not recognized as pair style, will be passed as arguments to
the pair style to the left. for example, if you don’t have lj/mdf
included in your executable, then the arguments to lj/cut will become
lj/cut 9.0 lj/mdf 6.0 9.0, which will lead to the “illegal pair_style
command” error message you are reporting.
