During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The ... En savoir plus
This tutorial shows how to couple three physics interfaces to model evaporative cooling. The effects that need to be taken into account are heat transfer, transport of water vapor, and fluid flow. The Wet Surface feature is used to implement the source term for the water vapor and to ... En savoir plus
Wastewater treatment is a several-step process for removing contaminants. Firstly, large, solid particles are removed through sedimentation, flotation, and filtration. And then in a second step, biological treatment causes the smaller particles to aggregate, forming so called flocs. ... En savoir plus
In this benchmark model for blood flow in a centrifugal pump, simulations are performed for several flow rates and pump speeds. The modeled geometry is taken from the FDA’s Computational Round Robin and the results are in good agreement with the experimental data. The computed shear ... En savoir plus
The Marangoni effect results in a slip velocity in the tangential direction on a fluid/fluid interface due to gradients in the surface tension coefficient. When the surface tension coefficient is constant, a two-fluid system may exist in static equilibrium. This is because the surface ... En savoir plus
The Ahmed body represents a simplified, ground vehicle geometry of a bluff body type. Its shape is simple enough to allow for accurate flow simulation but retains some important practical features relevant to automobile bodies. This model describes how to calculate the turbulent flow ... En savoir plus
This example simulates the thermodynamical evolution of moist air in an electronic box with the aim of detecting whether condensation occurs when the external environment properties change. The model imports measured data for the air temperature, pressure, and water vapor concentration. ... En savoir plus
This model simulates arc welding of a titanium plate made from an alpha-beta titanium alloy. During a weld pass, the material experiences a thermal transient, including both heating and cooling. Phase transformations are modeled, and the evolution of the phase composition over time is ... En savoir plus
This app demonstrates the following: Parametric geometry containing a geometry sequence with if-statements to produce different types of designs Options to set the mesh size A graphical user interface that includes different windows that can be shown or hidden Light Theme Water ... En savoir plus
This example models the casting process of a metal rod from liquid to solid state using the Non-Isothermal Flow multiphysics interface, which combines heat transfer and fluid flow. The model describes the fluid and solid flow and heat transport, including the phase transfer from melt to ... En savoir plus
