Today, materials science has an extremely important place in every conceivable industrial field, from automotive to catalysis, from aircraft technology to textile. However, designing a suitable material for the purpose at hand requires significant use of R&D resources. Computational materials science methods, which have been developed especially since the second half of the last century as support to trial-and-error methods, are now accepted both in the academic and industrial environment. In this training, one of these methods, classical molecular dynamics (MD), will be introduced and various examples will be made.
