External acoustic cavty meshing

Prashanth Setty

Hello everyone,

I'm currently working on a task where I need to perform acoustic analysis using a setup that involves a cube placed at the center of a sphere. The cube's surfaces are already meshed with 2D quads, and now I need to mesh the volume between the cube and the spherical boundary with 3D tetra elements for a subsequent acoustic simulation.
What is the best approach to mesh this volume, ensuring compatibility between the 2D mesh of the cube and a new 3D mesh?
Thank you in advance for your help!

Here is the help for the acoustic cavity meshing in HM:

I believe you will need to mesh the surface of sphere first.
