Hi Mesut, thanks for watching this video and we hope that you liked it. Galloping lines are indeed a great application of prestressed modal analysis. If you're interested to learn more we discuss it in our lesson on "Dynamic Instabilities" in this video: ruclips.net/video/p5avLKi0INY/видео.html

Thank You very much for this video. I understand that regardless of base analysis, the undeformed mesh is used for displaying modeshapes. Is there a way to visualize the prestress modal analysis results in the final state after prestress, and to verify the contact definition changes that happens during modal analysis (for example, interference resolution is done in the prestress step with nonlinear contacts, and then a modal analysis is performed)?
Which equation used by Ansys when applying static analysis (DC Voltage)? How that S (stress stiffening ) will be calculated? I would like to check the analytical calculation for capacitive ultrasonic micromachined transducer?

While watching this video, I thought of the electric wires in the air and the summer or winter wind that affects it.Thank you for presentation.

Nicely explained...sir what if use spring load in static structure to apply tension.?..can we use same methodology..?

Why you applied displacemt BC instead of Fixed support? Can we use fixed support?

In case of fixed support, the rotational degree of freedom at support is also constrained.
Fixed or not fixed will depend on real support condition. This is just a demo
How to get vibrational stresses ( real) from modal analysis?

You will never get real stresses from modal analysis. Please study by yourself the meaning of modal analysis.
You have to do a random, harmonic or transient analysis to get stresses.
