Hello
At the beginning of this year, I'm looking at the flow simulation module.
I have performed several calculations on fluid diffusions on nurses with, the results are close to the physical model (gripper by suction cup).
Out of curiosity I would like to print different acoustic horns to record the gain obtained in a deaf chamber and modify speakers.
The boundary condition (input and output) validates the x2 gain but I don't get a value in sound power because I don't power the model correctly.
Has anyone looked into the question to translate a level of Db at the entrance and check the number of DB obtained by the horn at its exit;
I have the whole approach with an EXCEL spreadsheet and the resource of its author, but to pass everything under Solidworks it's more tricky. I keep looking.
Thank you for the possible help and happy new year to you;
Spectrum.
