Dynamic Tensile test of molecule through MD

Hi!! I'm new here.
Does anyone know how to do the tensile test and calculate the strain energy during the process through MD in Material Studio?
I have tried to construct a unit cell,  put the molecule inside, and then had the unit cell deformed.
I calculated the total energy but  someone told me that what I did was not  the "dynamic" tensile test.
Is there anyone can help me? Thanks
