How to control displacement of multi-node?

[jhj]

I have a question about openseespy.

I want to give the initial displacement to multi nodes at the same time.

I looked it up and used the displacement control to give initial displacement, but it was only available on one node.

Does anyone know a good way to control multiple nodes at the same time?

I will be waiting for your reply.

You can use sp constraints inside a load pattern: https://portwooddigital.com/2021/02/07/ ... d-control/
