Many thanks for the video!

[@augustovidal4417]

Thank you, very useful presentation!💡

[@siyuanpei7451]

very good explaination sir

[@yosephtekle9967]

Thank you very much sir!

Hello sir, thanks for your sharing... I would like to ask is it possible to do the opposite of what you did in this video? I mean, I want to get the modal effects of a fluid domain (water) when a propeller and shaft system working in it. I need to rotate a motor which is connected to a shaft and a propeller inside a water environment and see how the natural frequencies of motor-shaft-propeller system change.

It was so good. I want to get the acoustic pressure from the vibration of a beam. Can you help me?

[@musaibrahim9845]

amazing.... thank you sir.. really appreciate your great effort

[@yangsun610]

hello, thank you for the video, based on this model, could you do the topology optimization of the plate? the objective function is to reduce the sound pressure of somewhere, that will be great!!!!!!

[@Rene_Christensen]

That Will likely not work as topopt introduces holes and hence there would be air going through the plate which requires special consideration

[@Rene_Christensen]

For your case, it is really acceleration not velocity that is linked to acoustics, when looking at curves. But very Nice presentation

very good explained sir thank you

How can we do two way coupling using ansys workbench? Could you please upload video on it?

[@smile09508]

Thank you.

Hello, I want to do the random vibration analysis of the guitar to find out the deformation and stresses generated in the guitar due to plucking the string of the guitar. So can you please guide me on how to do that means it comes under the NVH problem or just I have to perform the modal>harmonic and >Random vibration. As I have the input frequency of one string that apply on the string so what I do for that

Do we need cfx or fluent to be installed before conducting acoustics simulation?Which solver does the harmonic acoustics simulation uses?

[@OzenEngineeringSimulation]

No need for CFD software. Vibroacoustic is a capability of Ansys mechanical enterprise.

[@musaibrahim9845]

why can I get the Imported load in harmonic acoustic analysis? I'm using Ansys 18.2

How we can make enclosure for 2d element

[@stefaniamagnettigisolo5775]

good morning. Please, does someone know what to do when this error occurs: "reference to an object not set to an object instance". It occurs when I try opening Ansys meshing, and I don't know what to do, I cannot understand why it happens now.... please, I am desperate!

[@surabhisaxena1856]

Can anyone help me with dam modal dynamic analysis using reservoir as acoustic medium

You should understand that if someone watches your video it is because they do not know how to use Ansys well. Your video is interesting and complete, but it is not educational at all. To follow what you say, you need to stop the video every 5 seconds and go back very often. I think you need to make the videos like this but they need to be explained very slowly, also using English that is understandable to everyone and not just native speakers. A video like this is of practically no use as it teaches nothing to the less experienced and the more experienced are not needed.
