Thanks!!!!!!

Thanks alot for your hard work!
I am working on my thesis that is about (FEM and design of metaconcrete for acoustic performance), and I have to get the resonant frequency for the metaconcrete model.
Please let me know if you help me!
I am working on this thesis research models for metaconcrete:
S.J. Mitchell. Metaconcrete: Engineered aggregates for enhanced dynamic performance PhD thesis.
California Institute of Technology, 2016.
I need to get the resonant frequency for the model in page 28 of the mentioned reference thesis.
If it is possible, please make a video for these kind of models.
