Dear STKO,
When I use the Stko to conduct a seismic analysis via Opensees MP, a MPCORecorder FATAL Error: trial_ fiberdata. size () is happened. So what is wrong with it, could u help me to solve it.

When I close the MPCO recorder, this error is solved. So how can I solve it?

We just realized that due to a recent change in the Aggregator section in the latest OpenSees version, it gives wrong values for the MPCORecorder.

We already fixed, and before the next webinar in January you will be able to download a new OpenSees-Solvers installer from prof. tarque's website with this bug fixed.

In the meantime, do you really need the section aggregator? If not, you can just use beam-column elements without shear-deformability, otherwise you can record only a region of your model that does not include the elements with the section aggregator
