Hi
I have a cabin with a internal combustion engine in it. I consider IC engine as a source of sound with known characteristics. I want to simulate sound propagation inside cabin and minimize sound pressure level (SPL) in a certain position using different sound insulator (or absorber) on cabin walls.

Is it possible to do it by CFX or fluent? which one has more capability in this field?
I studied fluent and CFX documentation but I didnt find the answer of my question.

Thanks to all
Ali

Using a CFD code to do acoustics simulation is like buying a Ferrari to pick up the shopping. So both Fluent and CFX can do this sort of simulation, but unlike a Ferrari a CFD code will take forever on this simulation.

I recommend you investigate specialised acoustics modelling software like SYSNOISE. There are plenty of others as well. They are what you need for this type of simulation.
