The fluid flow interfaces display the Absolute pressure, which is the sum of the relative and reference pressure levels. These allow for the modeling of tunnel currents through insulating walls and the accumulation of charge on the floating gate. Tunnel currents There are two boundary conditions: Insulator Interface and Floating Gate. Spontaneous emission The new optoelectronics interfaces account for spontaneous emission in modeling direct band-gap materials. A flow interface such as the Fracture Flow interface can define the flow. The Fracture feature allows you to define the fluid and solid parts as well as the flow properties. It also provides a lumped model that can be used for cost-effective modeling. The Fracture feature allows for the thickness of fractures to be represented in the geometry. Every interface that uses a relative pressure internally can be set by the user at the physics interface level.įractures: The new Fracture feature models heat exchange in fractures using a thin porous media. All fluid flow interfaces announce the absolute pressure to eliminate the possibility of inconsistent reference pressure definitions within different components. Accumulators can be used in conjunction with the Moving Mesh interface so that the geometry can be deformed based on the flux particles onto the surface. An Accumulator, for example, can calculate the momentum flux at a border, which can be used to calculate pressure. This allows for efficient counting of collisions with walls and can be used to calculate the flux of any particle property at the border. The accumulated variable is only determined at the boundary and can only be changed by particles interacting with it. Fallback Conditions on Inlets: The Inlet node does not override the settings of Wall or Outlet nodes sharing the same selection.Īn Accumulator can also be added to an Outlet, Wall, or Axial Symmetry boundary. Your applications can be as complex or simple as your design requires. The application’s inputs and outputs can be controlled by you. A flexible Method Editor lets you program custom commands. This user interface is created using click-and-drag-and-drop operations. You can simply choose one of your existing models and create an intuitive interface for your application using the Application Builder. The Model Builder allows you to combine multiple physical elements in any order, allowing for simulations of real-world phenomena. This software platform allows you to create physics-based simulation models and applications. You can also download COMSOL version 5.1 today to get the most current technology in simulations. Comsol Multiphysics 5 FeaturesĬheck out the release highlights for the latest information. The frequency, intensity, and direction of incident rays can affect impedance and absorption. This includes combinations of diffuse and specular reflection. It is possible to assign various wall conditions at exterior boundaries. The properties of the media where the rays propagate may change over time within domains and at borders. To ensure backward compatibility, older models with Disappear wall conditions are automatically added to the Model Tree. This allows for custom settings to be applied to particles that return to an inlet boundary later.
