Exterior acoustic sphere mesh for motor acoustic analysis


Hi,
I am doing acoustic analysis for motor. When I mesh the gap between a motor component and a sphere at 1 meter distance using 3D tetra elements, it works fine (as shown) . But while doing the same with full motor, I am getting error in meshing. If anyone can help with this, it would be great.
Thanks

Hi sir,
The error message is as follows:
'Tetra Mesh failed error=-1, 4043 failed elements saved.'
The model is also shared to you via your FTP link.
Please help
Thanks


Hi Mayur,
You can see that there are 6 failed volumes. This could be because of the geometry. Try with a different element size and check if that helps.


Sir I am trying all the possible elements sizes from last 3-4. Still stuck with the errors
