Structural Analysis Presentation, General IntroductionStructural Analysis Presentation, General Introduction

This presentation gives an overview of the capabilities of COMSOL Multiphysics within the area of structural analysis. The presentation mostly covers the functionality of the Structural Mechanics Module - but also touches on what is...

Cooling and SolidificationCooling and Solidification

In this model, continuous casting processing of a metal rod from melted to solid state is modeled. The model describes the fluid and solid flow and heat transport, including the phase transfer from melt to solid. This phase change...

RF Introductory Tutorial: Step by Step Modeling of a Periodic StructureRF Introductory Tutorial: Step by Step Modeling of a Periodic Structure

This is an introductory tutorial that shows how to model periodic structures using the COMSOL RF Module. Periodic structures such as gratings and etalons are widely used in optoelectronics and as filters. Periodic metamaterial...

Fluid-Structure InteractionFluid-Structure Interaction

This is a model exemplifying how fluid-structure interactions can be modeled using COMSOL Multiphysics. Viscous forces and the system’s pressure impose forces to the surface of a structure. The deformation in the soft structure is not...

Forced Convection Cooling of Horizontal Circuit BoardForced Convection Cooling of Horizontal Circuit Board

In this suite of models, temperature distribution and fluid flow field is modeled with the General Heat Transfer and the Non-Isothermal Flow application modes. By modeling the fluid flow and heat transfer simultaneously the convective...

Fluid-Structure Interaction with Two Fluid PhasesFluid-Structure Interaction with Two Fluid Phases

The following example demonstrates techniques for modeling a fluid-structure interaction containing two fluid phases in COMSOL Multiphysics. It illustrates how a heavier fluid can induce movement in an obstacle using the arbitrary...

Piezo-Acoustic TransducerPiezo-Acoustic Transducer

People that use piezoelectric transducers are interested in phased-array microphone, ultrasound equipment, ink-jet drop actuators, drug discovery, Sonar transducers, bio-imaging and acousto-bio-theraputics. Basically anyone who is trying...

Simulating a Generator in 2DSimulating a Generator in 2D

In this model, a rotor with permanent magnets and a nonlinear magnetic material rotates within a stator of the same magnetic material. The generated voltage in windings around the stator is calculated as a function of time. COMSOL...

Free Convection in a Water GlassFree Convection in a Water Glass

This model treats the free convection and heat transfer of a glass of cold water heated to room temperature. Initially, the glass and the water are at 5 °C and are then put on a table in a room at 25 °C. The nonisothermal flow is...

Nonlinear Magnetostrictive TransducerNonlinear Magnetostrictive Transducer

Magnetostrictive transduction is used in sonars, acoustic devices, active vibration and position control and fuel injection systems. The transducer has a steel housing enclosing a drive coil. A magnetostrictive material is placed in the...
