Example Models

Fluid-Structure Interaction in a Network of Blood VesselsFluid-Structure Interaction in a Network of Blood Vessels

This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to...

Simulation of a Microrobot, 3DSimulation of a Microrobot, 3D

A microrobot's leg, which structurally moves due to the rapid application of heat, is modeled in this example. Heat is generated by an electric current and propagates by conduction through the leg and, due to thermal expansion and...

Eigenvalue Analysis of a CrankshaftEigenvalue Analysis of a Crankshaft

This model describes a modal analysis of a crankshaft. The pistons’ reciprocating movement is transferred to the crankshaft through connecting rods by means of crankshaft throws. The forces, torques, and bending moments, which are...

3D Fluid-Structure Interaction Simulation of an Obstacle in a Fluid Channel3D Fluid-Structure Interaction Simulation of an Obstacle in a Fluid Channel

In this model, fluid is flowing through a channel containing a flexible obstacle. Due to the viscous and pressure forces asserted by the fluid, the obstacle bends. With the obstacle undergoing a large deformation, the fluid flow domain...

Fluid-Structure Interaction in Aluminum ExtrusionFluid-Structure Interaction in Aluminum Extrusion

In massive forming processes like rolling or extrusion, metal alloys are deformed in a hot solid state with material flowing under ideally plastic conditions. Such processes can be simulated effectively using computational fluid dynamics,...

Viscoelastic Structural DamperViscoelastic Structural Damper

Damping elements involving layers of viscoelastic materials are often used for reduction of seismic and wind induced vibrations in buildings and other tall structures. The common feature is that the frequency of the forced vibrations is...
