Hi!

Is it possible to retrieve a mode shape when an eigenfrequency analysis has been run? I am correctly getting all the frequencies and periods, but I am unsure if it is possible to save the deformed structure in the first mode.

Perhaps NodalVibration component? But I am unsure how it works

Thank you!

I believe i solved it - i forgot to choose Nodal Vibration in the analysis setup

You are right 🙂

If you want, you can start using our LiveLink which will allow you to seemlessly work with an open instance of FEM-Design

Hi @MarcoPelle

The LiveLink is working perfectly fine for me.

However, I am generating a large number of models and doing modal analyses, and I would like to save the mode shape for each model that I am generating.

I am a bit unsure how to plot the mode shape of a structure in Grasshopper using the NodalVibration results component. Can you provide some guidance? 🙂

Hi @AKiaer

Have a look at the following example 🙂

The idea is to use Key-Value search to do remapping between results and FEM model
