Generalized stiffness

Hey,


I had a doubt regarding the units for generalized stiffness that can be observed from the .out file. I did the modal analysis of a student car and required the generalized stiffness for 1st 10 modes. The material properties i entered is as follows: Steel - E = 210000, v = 0.3, rho = 7.83*e-9. 

 

I also had a doubt regarding the torsional stiffness. So basically the formula is stiffness = applied torque/angle of twist. The post-processing result gives me the displacement for torsional load case. I want to know how can I calculate or view the angle of twist from hyperview post-processing?

 

Any help in this area is highly appreciated.
