This tutorial model illustrates how one can couple the OpenFOAM CFD solver with the FEATool Multiphysics FEA solver. In the model a stream of cool air is heated while flowing through a tube and fin heat exchanger. Due to several symmetry planes only a small section of the full heat exchanger geometry actually needs to …

Stress Distribution in a Solenoid

This multiphysics model examines how magnetic forces give rise to stresses in a long thick cylindrical solenoid. A current density of 106 A/m2 is running through a wound coil with 1 cm inner to 2 cm outer radii. The material of the coil is assumed to have a modulus of elasticity of 1.075⋅1011 N/m2 and Poisson’s …

Simulation of Heating to Promote Drug Mixing in the Eye

The leading cause of central vision loss in the developed world is from age-related macular degeneration (AMD). Although certain types of AMD can generally be managed with injections of anti-VEGF agents, the treatment is sometimes ineffective. The linked study examines how this type of treatment potentially can be …

Heat Induced Stress in a Brake Disc

This multiphysics model examines temperature and heat induced stresses for one braking cycle in a brake disc assembly, and involves coupling of the stress-strain and heat transfer physics modes. The braking process consists of applying a brake pad to the front part of the disc which induces heat through friction, and …
