Re: MultipleSupport output
Did you use Transformation constraint handler?

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 following error occurred when using structural models to validate newly developed materials
That's coming from the eigenvalue solver (DSAUPD), not sure why though.

Re: Simultaneous multidirectional loading
If you have doubts, perform simple analyses and check reactions and other easily verifiable responses.

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.

I see. Your model has no mass.

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.
