If i have accelerometer data which are the analysis i can run ?

In the hypothetical case i have accelerometer data, which are the analysis i can run?How can i import the data to feed into the model? How can i assign said data to the nodes of my model, where i need them to be? I searched around the forum but many of the documentation files say that other programs where used? In case CA cannot do that and needs some kind of conversion,which are these programs?

Hi,
I don't have much experience to say but you could do Linear Dynamics and Harmonic analyses. Assigning measured data to nodes means applying velocities, accelerations etc to nodes. I think you can do that with CREA_CHAMP and some python coding.

Thank you very much for the quick responce! For the dynamic linear analysis i found the DYNA_LINE command but i cannot seem to find it inside CA, did it change? Is the DYNA_VIBRA the correct command?!

Hi,
In version 13 it used to be DYNA_VIBRA. It may have been changed to DYNA_LINE in version 14.
Also you could do modal analysis, frequency response, transient response and random vibration response.
You can check here to see some types. https: / \www.youtube.com/\watch?v=Ddc3Kr6GDgI
