This video seriously helps me a lot, I use it to simulate another model and I meet a problem: when I export 1D plot, y-axis is certain(200-400THz), how can I change it? I want to get the result in the frequency(0-200THz). Tks for your generous help!!

This video is very helpful to me. I want to consider the band gap diagram of the periodic structure under the action of upper pressure. However, I gave the boundary condition - pressure, but I did not get the desired result. I don’t know if the blogger has any good ideas. ?

Can you help me what to do if my crystal has no repetition in z direction and instead has some fixed height.

Similar situation but bandgaps in 1D photonic crystal? What parameters must i add instead of mechanical?

How to plot a graph with only the frequency of transverse wave? Or it only can plot the graph with both wave?

Could you tell about the changes we need to give if the phononic crystal we consider have only finite number of unitcells?

The bandgaps can be obtained for periodic boundary conditions i.e. for infinite repetitions of unit cells...for finite repetition of the unit cells, the Frequency response curves are plotted and compared with the range of frequency bandgaps.

Could you please say how we can input the number of the unit cells repeating in the phononic crystal? I was trying to analyse phononic crystal with finite number of unitcells in it? But I couldn't find a suitable boundary conditions for this.

Thank you for this video. Is it able to draw such dispersion curves using Abaqus?

Unfortunately not...but you can get FRFs in Abaqus

@@sanjaykumawat8734 Thank you. Is there any way to apply the Floquet-Bloch boundary condition (Floquet periodicity in COMSOL) in Abaqus?
