How fast does a Calrod heat up and how high are the stresses during heating? To answer these questions Veryst Engineering developed a coupled electric-thermal-structural multiphysics model of the Calrod, accounting for conduction, convection, and radiation.
Efficient ventilation can reduce a building’s energy consumption and minimize airborne pathogen transmission in hospital rooms. Veryst used computational fluid dynamics (CFD) to simulate ventilation in a hospital room as well as the dispersion of particles and droplets.
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.
The main environmental factor affecting a premature neonate is thermo-neutrality, as the baby is incapable of regulating and maintaining his/her body temperature at a constant level. Veryst developed a computational model of heat transfer inside an infant incubator to optimize its design.

Radio frequency tissue ablation is a commonly used and minimally invasive tissue treatment procedure. Accurately modeling this kind of coupled multiphysics problem is often challenging.

The microelectronics packaging industry relies heavily on adhesive bonding to assemble electronic components. Veryst built a COMSOL Multiphysics model of a thermocompression bonding process to help reduce bonding cycle time by simultaneously optimizing material and process variables.
When would an automotive disc brake need to be replaced? The continuous frictional sliding between two deformable surfaces leads to wear accumulation and ultimately failure of the weakest component. However, wear modeling is not readily available in most finite element codes. Veryst developed a wear model in COMSOL Multiphysics using differential equations for the wear depth based on a modified version of Archard's law.
Veryst assists clients with the selection of adhesive materials, development of bonding processes, and mechanical analysis of interfaces.
