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.
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.
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.
Veryst has strong acoustic simulation expertise in a wide variety of applications, including medical devices and wearable technology. In many cases, acoustic problems cannot be solved adequately using a single-physics approach, and Veryst has extensive experience in solving multiphysics problems involving acoustics.
Veryst provides expert consulting services in modeling electromagnetic fields. Our expertise includes modeling electrostatics, magnetostatics, rotating machinery, and similar electromagnetic devices for power, energy, automotive, consumer electronics, biomedical, and many other industries. We use advanced numerical techniques to design, optimize, and validate our clients’ electromagnetic devices to function as digital twins.
Veryst offers a comprehensive approach to solving problems in microfluidic device development. We employ an array of modeling tools, such as scaling arguments, analytical formulas, computational simulations, and laboratory testing to inform the design and integration of common components.
