Time steps in dynamic analysis

Time steps in dynamic analysis

Time steps in dynamic analysis

(OP)
How can I modify the time steps in dynamic analysis?
I am analyzing a 40-story building subjected to wind load and it's taking too long to complete the analysis. (8 hours and the output files are 7 GBs altogether!!!)
Is there any way I can reduce the processing time?

RE: Time steps in dynamic analysis

You modify the number of time steps under Define>Time history cases. 40 stories would be a large model. If you overmeshed the floors and walls, that can also hurt run time.
