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: A C++ ElasticBeam3d problem

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?
