Your model (free sample model) was used and it runs. Since the FPS isolator depends on the velocity, the Isolator2 element must be used. When I use Isolator2 element instead of plst element, it does not run.

Hi,
I modeled a base-isolated structure equipped with FPS isolator as a SDOF system. The FPS isolator is modeled using the link element of “Isoator2”. But SDOF model does not run under earthquake excitation.
