Advanced Testing and Modeling of Polymers for FE Simulation
This course is intended for finite element (FE) engineers that simulate polymers and are interested in advancing their modeling skills to the most advanced material models available for polymers.  We will review the foundations of continuum mechanics for material modeling and dive into advanced material model calibrations, including inverse calibrations, failure modeling, and anisotropic material modeling.
Testing and Modeling of Polymers for FE Simulation
NOTE Date Change! This course is intended for finite element (FE) engineers that simulate polymers and are interested in advancing their modeling skills beyond hyperelastic material models.  The class covers the foundations of continuum mechanics for material modeling, including hyperelasticity, metal plasticity, linear viscoelasticity, and advanced viscoplastic material models.  The class also covers test methods and discuss how to design test plans for material modeling. 

Case study

Active Mixing in a Microwell by Repetitive Pipetting
A simple way of mixing small volumes (microliters or milliliters) of reagents is by repeatedly dispensing and withdrawing solution from a microwell or tube. In this case study, we used a two-phase multiphysics simulation with coupled fluid flow and mass transfer to analyze the efficacy of this active mixing process.
Chemical Carryover in Microfluidic Devices
Removing reagents or sample from a previous processing step via a wash cycle is a common challenge in microfluidic assays used in diagnostic, genomic, biomedical, pharmaceutical and other applications. This case study shows how finite element simulations may be used to predict and optimize wash cycle performance.
Concentration Gradients in Microfluidic Devices
Controlling spatial variations in chemical concentration is important for designing and operating many microfluidic devices across a wide range of industries and applications including diagnostics, genomics, and pharmaceutics. In this case study, we show how simulations may be used to quantify and control concentration gradients in microfluidic devices.
Designing MEMS Gyroscopes for Manufacturing
Manufacturing variations are of critical importance in MEMS design. In this MEMS gyroscope case study, Veryst created an approach to look at the effect of a range of manufacturing variations on MEMS devices using the same mesh. We also use semi-analytic equations to enable scalable modeling of the gyroscope electrostatic actuation and pick-off (which senses the motion produced by rotation).
Insufflation Analysis
To compare the performance of two gas humidification devices, Veryst Engineering performed gas flow testing, device examination, and CFD analysis.
Laminar Static Mixer Analysis
Laminar static mixers are often employed in industrial environments when the mixing of two or more fluids is required. However, their performance is impossible to analyze with a pure CFD approach. Veryst, in collaboration with Nordson EFD, developed a unique computational modeling tool to evaluate and optimize the design of such mixers.
Micromixing in a Multi-Inlet Vortex Mixer
Flash nanoprecipitation (FNP) is a novel method to produce nanoparticles for a variety of applications, including mRNA vaccine manufacturing. This case study demonstrates the high-fidelity prediction of micromixing rates, which are critical to controlling the size distribution of nanoparticles created using FNP.
Oxygen Transport and Cellular Uptake in a Microchannel
Oxygen transport is a key factor in the design of cell culture systems such as organs-on-a-chip, microphysiological systems, and bioreactors. In this case study, we use multiphysics simulation to analyze oxygen transport and cellular uptake in a model microchannel bioreactor.
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.
Scaling Yield and Mixing in Chemical Reactors
Scaling chemical reactions from the lab to pilot or production requires a detailed understanding of the physical system, which frequently involves heat transfer, mass transfer, reaction kinetics, and fluid flow. This case study illustrates how multiphysics simulations can support design decisions involved in scaling up chemical reactors.
