Applying spring force in atomistic level simulation

Hi everyone,

I want to apply a moving spring force to a group of atoms in my simulation system. But i do not work in DPD. Would you please help me about this? Generaly is it possible to apply a spring for streered molecular dynamic (SMD) simulation in Materail studio, while the simulation is carried out in atomistic level not DPD?

Best Regard
