Thermally Loaded Beam

In this example you will build and solve a 3D beam model using the 3D Beam interface. This model shows how a thermally induced deformation of a beam is modeled. Temperature differences are applied across the top and bottom surfaces as well as the left and right surfaces of the beam. The calculated solution is compared to the analytical solution.

Water Purification by Silver Complexation

Many industrial processes leave remainders of toxic dissolved metal ions in process flows. A common method for removing metal ions from water is complexation. This model example shows a purification reactor where silver ions are complexated to diamine-silver for removal. Ammonia (L) is added across a membrane in a tubular reactor in order to remove silver ions (M) from a water stream. A ...

Outgassing Pipes

This benchmark model computes the pressure in a system of outgassing pipes with a high aspect ratio. The results are compared with a 1D simulation and a Monte-Carlo simulation of the same system from the literature.

Marangoni Effect

Marangoni convection occurs when the surface tension of an interface (generally liquid-air) depends on the concentration of a species or on the temperature distribution. In the case of temperature dependence, the Marangoni effect is also called thermo-capillary convection. The Marangoni effect is of primary importance in the fields of welding, crystal growth and electron beam melting of metals. ...

Molecular Flow Through an RF Coupler

This model computes the transmission probability through an RF coupler using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability determined by the two methods is in excellent agreement with less than a 1% difference. This model requires the Particle ...

Multicomponent Tubular Reactor with Isothermal Cooling

This application uses the Chemical Reaction Engineering Module to study an elementary, exothermic, irreversible reaction in a tubular reactor (liquid phase, laminar flow regime). To keep its temperature down, the reactor uses a cooling jacket with a constant coolant temperature. The steady-state behavior of the reactor is investigated. The application visualizes how the Chemistry and Transport ...

Electrodeposition on a Resistive Patterned Wafer

This example models time-dependent copper deposition on a resistive wafer in a cupplater reactor. As the deposited layer builds up, the resistive losses of the deposited layer decreases. The benefit of using a current thief for a more uniform deposit is demonstrated.

Thermal Bridges In Building Construction - 2D Square Column

This example studies heat transfer in a square column. Cold and hot temperature conditions are applied to the boundaries. Due to the symmetry of the problem, the geometry is simplified to half of the square. The temperature field is compared with the analytic data. This example corresponds to the case 1 described in the European standard EN ISO 10211:2007 for thermal bridges in building ...

Biomechanical Model of the Human Body in a Sitting Posture

The dynamic response of a human body in any vibration environment can be predicted using this biomechanical model. In the automobile industry for instance, this model can be used in ride quality simulation and designing vibration isolators such as seats. In this example, a biomechanical model of the human body is developed to evaluate the dynamic response to the vertical vibrations in a sitting ...

Pacemaker Electrode

This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in SolidWorks by using the LiveLink interface.
