Hello everyone! I am building an acoustic model with a plate and an acoustical environment (sphere) around.. I would consider a mapped mesh on the plate and a tetrahedral mesh for the sphere. It is possible?

Hi Giada,

Yes, you can use a swept, structured mesh for the plate and mesh the remaining geometry (the surrounding sphere) using a tetrahedral mesh.

Best regards,

Magnus

Hello Magnus, how is it possible? When I set a mapped mesh for the plate and after a the tetrahedral mesh for the sphere the second is overwritten to the first..

Hello Giada,

First create a mapped mesh on the plate and then a terahedral mesh on the remaining geometry (that is, the sphere surrounding the plate). Don't continue by meshing the entire geometry using tetrahedra.

Magnus

Thank you Magnus, I will try again. Thank you very much. To cut the geometry and visualize both meshes you have used a workplane right? Thank you in advance! Ps. Sorry but I have been working with Comsol for only 1 month and I am learning. Best regards, Giada

Hello Giada,

I see. There is so much functionality to explore!

I used a Clip Plane to interactively look "into" the 3D geometry. It is available in the most recent versions of COMSOL Multiphysics (5.6 and 6.0).

Best regards,

Magnus
