For acoustic radiation analysis ANSYS Acoustic Guide (R15) suggests use 0,2*lambda of the main frequency but I was told to consider 1 lambda. ANSYS suggestion would surely decrease the size of the whole model.
My research supervisor G. A. Askaryan taught me many years ago that the good scientific result impresses scientific community if you managed to improve physical effect at least twice, and it is better if three times or five times, and it is even better much. Dear Fabio, I answered your question?
Thank you so much Alexander! So, I would like to ask you if you could be a little more specific in your answer. What I understood based on what you say is that it would be better if I use the bigger model to ensure that my results are reliable, isn't it? Thank you again.
When you asked about big model, I remembered at once my grandmother who taught me: "Sasha, be careful with big subjects therefore bypass the tram in front, and a horse behind. That it well kicked you and you grew wiser".
