How can I get the modes in a dynamic (modal) analysis?

Hi,

with the Ansys Help I can see the graphic modes. But I need them as a vector (or the modal matrix) to get with the eigenfrequencies the mass matrix and the stiffnessmatrix of a dynamic system.

How can I import those modes for example into Matlab or into an excel program.

I  need the modeshapes to get the matrices with following equations:

M*x_dotdot + C*x = F(t)

then I transform

x(t)=Phi*q(t) (Phi is the modal matrix)

and I'll get

Phi'*M*Phi*q_dotdot + Phi'*C*Phi*q = Phi'*F(t)

this is

I*q_dotdot+Lambda*q=Phi'*F(t)

with I as the Unity Matrix and Lambda with the quadratic eigenfrequencies in its diagonal.

Then I can calculate this with matlab back and I'll get the matrices.

Greetings
