Tubular reactors are often used in continuous large-scale production, for example in the petroleum industry. One key design parameter is the conversion, or the amount of reactant that reacts to form the desired product. In order to achieve high conversion, process engineers optimize the ... En savoir plus
This tutorial demonstrates how to partition a 3D part to create a swept mesh. The example explores different strategies for partitioning the geometry, and demonstrates how to combine hexahedral and tetrahedral meshes. En savoir plus
This setup demonstrates how the characteristics of turbulent flow in a channel are modified by the presence of an adjacent porous region. Asymmetric velocity profiles, higher turbulence levels, and higher friction coefficients both at the solid wall and the fluid-porous interface are ... En savoir plus
This is one of the two models from the blog post about heat transfer in the subsurface: Coupling Heat Transfer with Subsurface Porous Media Flow Note: Poroelasticity is not included here. En savoir plus
Shape optimization with respect to fatigue properties is not supported, but fatigue properties are well correlated with the maximum stress. The model demonstrates how optimization with respect to a p-norm of the von Mises stress can be used to improve fatigue properties without ... En savoir plus
This app demonstrates the following: Multiple components (1D and 3D) in a single app Using the same choice list in the app as in the model using Data Access functionality Output numerical results for a specific time step using a combo box The app combines the Ray Optics Module and ...

This tutorial model solves for a hydrogen plasma created in a microwave cavity. The model computes the fluid flow and gas heating self-consistently. En savoir plus
This tutorial digs deeper into the investigation of rate capability in a battery and shows how the Lithium-Ion Battery interface is an excellent modeling tool for doing this. The rate capability is studied in terms of polarization (voltage loss) or the internal resistance causing this ... En savoir plus
This model demonstrates how to define Earth properties that are spatially varying on the planet. A satellite in orbit experiences solar, albedo, and planetary infrared (IR) loads, where albedo and planetary IR can vary with latitude and longitude. In this example, these inputs are read ...

Galvanic corrosion between two different phases (alpha and beta phases) in a metallic (magnesium) alloy is simulated for a representative cross-sectional microstructure configuration. A key feature in the model formulation is the implementation of both anodic and cathodic regions at ... En savoir plus
