Good morning everybody,

I have a question about Caesar II.

We have a Casear II model of a pipework. We know that in the reality a random force is applied to the pipework. Therefore, we don't have a time history of the force.

However, we do have a PSD and the frequency of the force.

Is it possible, in Casear II, to apply these data to a section of the pipe and obtain a PSD of the displacements and stresses?

I hope to have been clear enough.

Thank you very much.
Kindest regards,
Ilario

I am uncertain of your term PSD.
CAESAR II can evaluate response to a harmonic load. This would be a dynamic analysis. You provide the force vector at a node and it's frequency.

Sorry for the very late answer.

PSD means Power spectral density and it represents the distribution of energy in the frequency domain.
