Hallo Everyone
I have a model of a loudspeaker enclosure in solid. Due to the time taken in the simulation in 3D, Acoustics solid interaction module, i am thinking of using the Acoustics shell interaction module as used in the vented loudspeaker enclosure model from comsol tutorials.
I am using comsol 5.1 and i am trying to use the geometry-convert-midsurface to convert my solid to shell model. Is it the right approach? Or do i need to do some more processing in between to convert my solid model to shell model,

Hi,
Getting the midsurfaces is one possibility.
But it is often easier to place the shell mesh on the top or bottom surface of your geometry and use the Offset option in the Shell interface to indicate the location of the midsurface. For Acoustics problems, this strategy can also have the advantage that the acoustic domain is not increased by 1/2 of the shell thickness, which it will be if the shell is modeled on the midsurface.

Henrik

Hallo
thanks for the quick reply, but i am still quite new to COMSOL , so could you please explain me in bit details about the process you suggested. Thanks in advance.

Hi,
You can find an example of shell modeling using offset in the Application Libraries. The model bracket_shell (under Structural Mechanics Module-> Tutorials) displays this technique. Actually, this example is a combination of solid and shell modeling.
