How to plot freq response function for a node? 2

[DrBwts]

Hi,

I've run a steady state & dynamic frequency analysis & am now trying to get the frequency response functions (FRF) for particular nodes.

So far I have only been able to output accelerations & displacements for every node. As there close on 1/4 million nodes this isnt ideal.

What am I missing here?

What exactly do you mean with "frequency response functions (FRF) for particular nodes"? It it the frequency of his movement?

 

[DrBwts]

Range of nodal displacements at certain frequencies.

Sounds to me like a xy-plot of the displacement magnitude vs. frequency for such a node.

That's what I thought but whenever I try to create XY Data I get the following....

I assume you have other steps in the analysis, that act in the time domain. Use the upper right button in that dialog (or Results -> Active Steps/Frames) to deactivate such steps before.

Also think about complex results. Maybe you also have to switch the settings before. See Results -> Options -> Complex Form

Phew thanks that was driving crazy
