Temperature Loading of a Tapered Cylinder
This validation test case models temperature loading of a tapered hollow thick cylinder with a spherical bottom flange section. The solid object is assumed to be clamped vertically, but allowed to expand horizontally due to a linear temperature gradient. The stress in the z-direction at the bottom inner point is …
Electro-Osmotic Flow
This multiphysics example examines microfluidic flow and coupled mass transport due to electroosmosis in a channel with a T-shaped junction. With application of an electric field in a micro channel a flow effect is induced along the walls due to chemical reactions between the liquid and the wall material. This effect …
Multi-Simulation Heat Exchanger
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 …
Fluid-Structure Interaction - Elastic Beam
Fluid-structure interaction benchmark problem for stationary, laminar, and incompressible flow around a cylinder with an attached elastic beam. Although it is not possible to derive an analytical solution to these test cases, numerical solutions to benchmark reference quantities have been established for the beam …
Piezo Electric Bending of a Beam
Multiphysics simulation of piezoelectric bending of a laminated beam as for example can be found in actuators for MEMS (micro electro mechanical systems) devices. The model features coupled plane-stress and electrostatics physics modes with equations modified to account for the anisotropic piezo-electric coupling. The …
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 …
Heat Exchanger
This heat exchanger example illustrates the multiphysics modeling capabilities of FEATool. The model consists of a series of heated pipes surrounded by a fluid at a lower temperature, and features effects of both free and forced convection. Two types of physical phenomena are considered, fluid flow which is modeled by …
