 This page is discussed on the relativistic and nanoscale molecular dynamics simulations, Computer Physics Communications (2019, Ref. 1). Updated files of a non-parallelized code @cnt3em_3pCa.f03 for Maxwell equations, and a parallelized code @a_cnt3-3p7Ca.f03 
 for the Maxwell equations especially with the z direction are given in this directory.

 Each simulation code is suitable for the non-paralleled or parallelized 
 Maxwell equations with parallelized particles, which really depends on different architectures.
