Recorder behaviour

[EricsonEncinaZ]

Hello,

I know that once a recorder is defined it will save all converged steps, but I would like to save the building response at an specific event (roof displacement in this case). Currently the recorder saves all the converged steps and I post-process the data to get the forces at a the required displacements. Is there any way to make a recorder save just at specific displacements and not at every converged step?

Thanks

If you are running the analysis with a for loop, you can try defining the recorder just before the target displacement. You can do that with an if statement.

Thank you

don't use a recorder at all .. get whatever quanaty you are recording from the command line and write them to a file.

Thank you Frank, that is what I'm doing, it is way faster than define the recorder and then remove it.
