Fatigue Module?

Hey there,

I have been using COMSOL (for structural mechanics and some fluid mechanic) for about 2 years in my engineering classes (UCR). The project I am currently working on calls for fatigue testing and I would like to do simulations. After some research I learned that in order to do fatigue testing I will need the Fatigue Module. The Classkit (4.4) version of COMSOL does not have this. How do I get this module?

Thanks,

Chris
