Modeling Thermal Ablation for Material Removal
When certain materials are heated to a certain point, they go directly from the solid to the gas phase in a process called ablation. Learn how to model the thermal ablation process here.

Viscosity Ramping Improves the Convergence of CFD Models
Viscosity ramping can help decrease the computation time for your models by solving for higher viscosities and using the solutions as initial conditions for the problem at lower viscosities.

Model How the Bubbles in a Glass of Stout Beer Sink, Not Rise
Ever notice how the bubbles in certain kinds of stout beer sink to the bottom of the glass instead of rising to the top? We explain this phenomenon using fluid flow simulation.

App: Design a Geothermal Heat Pump’s Heat Recovery System
The design and installation of a geothermal heat pump often involves many different configurations, which can be easily tested with a simulation app. See an example in action here.

Improving Vascular Access for the Treatment of ESRD Patients
By combining CFD simulations with shape optimization techniques, biomedical engineers can better understand and predict vascular access for renal disease treatments.

Studying Transient Heat Transfer in a Fin Design with an App
A guest blogger and author presents a simulation app that he designed to study transient heat transfer in a nonprismatic fin.

Design Safe Wearable Technology with Heat Transfer Modeling
Wearable technology is more than just fitness-tracking bracelets and smartwatches. It is important to consider heat transfer when designing wearables that are safe for consumer use.
