What kind of Stress calculates in Forcite?

Dear Friends,

I am trying to find mechanical properties of some amorphous polymers.I have a couple of questions ,if anybody can help me.

What method is using by Forcite to calculate Stress ? 

for example  in  " SymmetrySystem->Stress->Eij(1,1) " , Is that a dynamic stress by using Virial stress or it is only a static stress?

What about the method is using in  MechanicalProperties  section (Modules->Forcite->MechanicalProperties),  is that a static method or dynamic method?

Thank you for your considration.
