Design and Simulation of a Catheter-Based Acoustic Ablation Device
Thermal ablation is a minimally invasive way to treat tumors, and simulating the physics of ablation can help in the design of ablation devices. Veryst designed and simulated a catheter-based acoustic ablation device relying on acoustic pressure waves to heat tissue to induce necrosis.
Immersed Beam Vibration
When a thin structure is immersed in a fluid, its natural frequencies, mode shapes, and damping characteristics may be significantly affected by the fluid. Predicting the dynamic behavior in this case requires a structural-acoustic analysis.
Phononic Band Gap Analysis
The call for structures that can selectively block acoustic waves of certain frequencies is growing, but their design is often inhibited by the lack of appropriate simulation tools in commercial FEA packages. Veryst developed a COMSOL Multiphysics model for unit cell band gap simulations, enabling the design and optimization of phononic band gap structures with target band gap width and locations.
