Command for adding tensile force to atoms in a simulation box


From the documentation i could find out airebo style is only for Carbon -Hydrogen atoms .But while using this it gives an error incorrect arguments for pair coefficients .While the syntax of pair_coeff is correct .The documentation says this error is "self explanatory "My script looks like this
