We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Kaushal,

 

  1. I am performing modal acoustics analysis
  2. The goal is to see the modes for a fluid sloshing inside a spherical diaphragm tank. See Image attached from [Sabaghzadeh, 2021]. The fluid is modeled using FLUID221 acoustics elements and the rest of it is solid. As you can see there is a large gap between the diaphragm (inside the tank) and the tank upper half. The other side of the diaphragm (lower side) is filled with fluid. So I am trying to create a contact between the diaphragm upper surface and the tank upper half section so that the diaphragm does not go out of the tank in any of the modes.
