Case Studies

Regulatory agencies such as the US Food and Drug Administration (FDA) require medical device manufacturers to follow rigorous simulation verification procedures to assess credibility of numerical simulations used to support submissions. In this case study, we simulate crimping of a Poly L-lactic Acid (PLLA) stent in the implantation process and demonstrate numerical solution verification.

Some of the most sensational goals in soccer history came from free-kicks and long shots. (Remember Roberto Carlos’ famous 1998 free-kick?) Veryst investigated the effect of friction between ball and boot, the ball’s internal pressure, and ball materials on the ball’s rotational velocity to understand ball/boot interaction.

How does a soft fluidic gripper perform when inflated and how does it interact with its environment? This is a challenging, yet essential, question to the design and integration of soft robotics in the industry. Veryst Engineering developed a finite deformation Abaqus model to study the behavior, performance, and stability of soft fluidic grippers, providing insight to the design and assessment of soft robots and devices.

Veryst can predict the ultimate strength and failure modes of design concepts generated using topology optimization and produced using additive manufacturing. We use advanced finite element analysis (FEA) that accounts for the nonlinear behavior of the material being used to make the part.

During sloshing, liquid exerts a dynamic force on the surrounding vessel, which may cause leakage or damage to the vessel or its supporting structure. We used a mesh-free smoothed particle hydrodynamics (SPH) method to predict liquid sloshing and its effect on the deformation and stresses in a vessel.

Many engineering applications require understanding the behavior of polymers under cryogenic temperature conditions. Veryst developed a test fixture and method to test materials submerged in liquid nitrogen (LN2) at its boiling temperature of -196°C.

Electroosmotic (EO) pumps are driven purely by electric fields and have no moving parts. Cascading EO pumps reduces voltage requirements. Veryst used computational fluid dynamics (CFD) and semi-analytical equivalent circuit theory to analyze the complex behavior of these pumps.

Thermal management is crucially important for battery performance in consumer products, electric vehicles, and grid-level storage systems. In this case study, Veryst used multiphysics simulations to evaluate different thermal management strategies in prismatic and cylindrical battery packs.

Veryst developed a diffusion model accounting for the different layers of the human skin in order to predict the drug concentration profile of a transdermal drug delivery process.
