I am using an EAM pair style and would like to manipulate the mass of an atom type. The docs for the EAM pair style say that the mass is read from the potential file and that this will override any values set with the mass command.
Is there any way to override this behavior and control the atomic mass within the script? Or am I stuck with creating a modified potential file for each mass?
You should use the mass command after the pair_coeff command to override the mass set by the EAM potential file.
Ok, that appears to have worked. Is it correct that I will need to do this every time the EAM pair style is defined? As in, if I checkpoint my run and resume it by loading a data file it will be reset to the mass in the EAM potential again and ignore the mass that was saved to the data file?
Yes
I understand now. Thank you for your help.
