Re: How to define damping ratio of vertical mode?

The modes dictate which directions get the target damping ratios. All the other modes get whatever according to the damping spectrum.

Re: The unit of a two-node link.

No units are assigned, you are responsible for units. Translational springs in two node link elements provide a relationship between force and deformation. Rotational springs - moment and rotation.

Re: Cannot Solve Eigenvalues

I didn't see that. You'll have to figure out what's going on. Start with simple models and build up from there.

Re: Cannot Solve Eigenvalues

There is an error in your model definition, e.g., insufficient boundary conditions or floating nodes.

Re: Ability to compile newer version of OpenSeesSP

You may want to try a virtual machine with OpenSeesSP already pre-compiled for Tcl and Python:

Even though it runs on LInux, you can access the virtual machine from Windows.
