initial conditions

[samearthquake]

Hi everyone

I want to perform a transient analysis, initial conditions are required in order to start step by step time integration. how can I define non-zero initial displacement and/or initial velocity for a particular DOF in my model?

Thanks

you could add some load to impose those displacements in a static analysis using either load control or displacement control, then simply remove the load pattern and start a transient analysis.
