Hello and thank you for your post! I tried to transpose your model to a bigger one for room acoustic purpose, unfortunately it didn't verify the helmoltz equation. Any Idea concerning the issue?
@@humansineducation4511 oh I see, thank you. However, there is an undefined variable x in the p_in equation when I simulate it. Btw I'm still working on this project and I have some questions regarding this simulation. Can I contact you via email? I'm very apreciate if you can help this problem, thank you
Hi I got a solution for this problem, Make sure to define the pressure for the thermovisucs model as p and the pressure acoustic as p2. this x is a direction
Thanks for your tutorial, it's very helpful i'm doing an acoustic simulation to find sound absorption coefficient too so please, can you tell me about value of variabel x in p_in equation ? because, when i tried your equation on my project it's got error : undefined variabel x

nice tutorial!
What is the formula for absorption coefficient?
Hello, You can find the corresponding equation and details in this article: aip.scitation.org/doi/10.1063/1.4941338
@@humansineducation4511 what is p_i and p_r it's unit is newton. They are incident and reflected forces.where can i find their expression

What is the result? How much it is different?
@@humansineducation4511 Thanks for your reply :) Is there any possibility for me to send you the file?
@@humansineducation4511 it's very far...400Hz instead of 80Hz
Could you explain where is the calculation of alpha in your model?
It is defined in variables.

On which topic you are working
I'm having the same problem. I can't read the variables properly so I'm getting errors. Did anyone solve this?
@@nikovkazaiz Did you find a soultion for that ? I have the same issue ??
Image quality is blurry :(
It will be clear within sometime because video is still processing. Thank you.
