I am using pair_style meam with the generic file library.meam with one or two element here Al and Si, present in library.meam file.
In both cases I have an error message : ERROR: Incorrect args for pair coefficients (src/MEAM/pair_meam.cpp:206)
My Lammps version is of Sept2021
I have attached the input script and the corresponding log file.
The file library.meam is copied in the working directory.
I understand that it should run without the 2nd file.
If the second filename is specified as NULL, no parameter file is read, which simply means the generic parameters in the library file are used. Use of the NULL specification for the parameter file is discouraged for systems with more than a single element type (e.g. alloys), since the parameter file is expected to set element interaction terms that are not captured by the information in the library file.
Adding NULL instead of the 2nd file does change the error message.
