Groundwater Oil-Lens Simulation with FEATool Multiphysics
Petroleum leakage has produced long-lived groundwater contamination in the Rey industrial area south of Tehran, where oil from refineries, storage facilities, pipelines, and other infrastructure has accumulated in and above the shallow aquifer. Oil present as a separate liquid phase on the groundwater table is called …
FEATool Stress Analysis of Lead-Core Ice-Ball Ablation
Melting of the submerged part of an iceberg, its keel, releases freshwater below the ocean surface, influencing water circulation, mixing, and local seawater conditions. Understanding how quickly the keel melts requires relating ice loss to seawater temperature and salinity. In her 2026 University of Manitoba …
FEATool Heat Transfer Verification of a Multi-PCM Passive Vaccine Cold Chain Container
How long can a vaccine container stay cool without electricity? Researchers at the Technological Institute of the Philippines investigated a passive container designed to maintain a vaccine compartment between 2 and 8 °C for 17 days in a constant 35 °C environment. The design combines vacuum insulation with phase …
Aortic Valve Stress and Strain Simulation with FEATool Multiphysics
Finite Element Analysis (FEA) of the aortic valve can be used to predict leaflet stress, strain, and deformation throughout the cardiac cycle. This is particularly relevant for congenital valve variants such as bicuspid and quadricuspid aortic valves, where altered leaflet geometry can produce asymmetric mechanical …
Battery-Free Solar PCM Tomato Cold Storage with FEATool
Keeping harvested tomatoes cool is difficult in off-grid tropical regions, where high ambient temperatures accelerate deterioration but reliable electricity may not be available. Solar-powered refrigeration can provide daytime cooling, but maintaining low temperatures after sunset commonly requires electrochemical …
Rocket Nozzle Design and Validation with FEATool Multiphysics
Small sugar-propellant rocket motors, often called R-Candy motors, provide an accessible platform for studying propulsion and nozzle design. Their relatively simple construction makes them suitable for educational and experimental rocketry, but predicting how combustion pressure, temperature, and exhaust flow interact …
Cooling Analysis of a Battery Pack Module
This example shows how to model a battery pack stacked with 20 prismatic battery cells. A heat transfer analysis will be conducted for the model where it is assumed that one of the battery cells is faulty resulting in significantly increased heat generation in the cell. Two different cases will be studied, one where …
Heat Conduction with Tabulated Thermal Conductivity
This heat conduction tutorial example illustrates how to use data from a (text) file in an equation coefficient. The tabulated data here represents non-linear thermal conductivity as a function of temperature k = f(T). Where the conductivity curve is given as sin(pi/8) to sin(3/4*pi) for temperature values between 280 …
Digital twin (DT) real-time framework with accelerated flow simulations
The research presented in the linked article introduces a digital twin (DT) simulation framework designed for smart kitchens to facilitate improved kitchen and usability design. A digital twin is a simulation process that integrates multidisciplinary and multiscale simulation through multiple sensors collaborative …
Structural mechanics FEA simulation for design of Push-Pull robots
This paper explores the design of “concentric push-pull robots” designed to make endoscopic surgery easier, such as biopsies or to removing polyps. In contrast to using colonoscopes which are difficult to maneuver, and may lead to longer procedure times and a higher chance of needing additional more …
