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
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.

Your vecxz is parallel to the x-axis of the element

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.

Re: Please help us to resolve the error!!
Check your boundary conditions and nodal fixities. You have a rigid body mode in your model.

Re: Mainshock-aftershock sequences
It's likely sendSelf and recvSelf are not implemented for that material. You can inquire with the developer.

Re: Mainshock-aftershock sequences
sendSelf and recvSelf are not implemented correctly for the elements and materials you are using.
Which elements and materials are in your model?

Re: 3DRCframe-Vertical frequency/period/eigenvalue
There is no difference between "horizontal" and "vertical" periods. Periods are periods.
Define mass and stiffness in the vertical direction and you will get an eigenvalue that corresponds to vibration in the vertical direction.

I don't know all the details, but check Table 5.1 and Figure 5.5 of the Haukaas and ADK PEER report shown on the wiki page.
