Dear Stephan Grein,
Thanks a lot for caring and offering a help. I appreciate that people such as yourself putting efforts to come here to help others and that is a nature of science. There is no shame to ask and actually people have the right to ask and learn as long as it is in the same area wether the question was advanced, basic and/or fundamental. People actually wouldn’t come here to seek an answer if they didn’t try to solve their problems by themselves. Professionals are supposed to be well educated to accept this fact not to help and then warn. However, I deleted LAMMPS from my machine for good. I am not interested to use LAMMPS anymore and waste people time as Axel Kohlmeyer claimed in his message.
