Structural acceleration in 3D

Please login with a confirmed email address before reporting spam


I am trying to establish the model of an isodynamic transducer. I used the tutorial of the loudspeaker driver as reference to do it in 2D before doing it in 3D. However, I have a problem with my 3D model :
- in the Solid, stress-strain (acsld) model, the coil and the membrane are the only ones activated with a fluid load on their boundaries,
- in the Pressure acoustics model (acpr), they are deactivated, they are solid domains but I cannot choose structural acceleration for their boundaries : they are deactivated (but it is not the case in my 2D model).
Do you know where the problem comes from or if I am mistaken ?
