What is mesh control edges Comsol?
What is mesh control edges Comsol?
Mesh Control Edges. Mesh Control Edges. Use Mesh control edges for precise control of the mesh in specific regions of the geometry, without affecting the geometry used for assigning physics. To fully resolve the gradients in a field in certain regions of a domain (2D) or on faces (3D), a finer mesh may be required.
What is a free tetrahedral mesh?
Free Tetrahedral. Add a Free Tetrahedral node ( ) to create an unstructured tetrahedral mesh. If no selection is specified, this feature creates a mesh on the remaining domains, boundaries, edges and points. You can control the number, size, and distribution of elements by using Size and Distribution subnodes.
What is swept Mesh in Comsol?
Swept meshing is a geometry discretization technique available in COMSOL Multiphysics for specific types of geometries, including thin geometries, geometries with bends, and models with little or no variation in a specific direction.
What does mesh do in Comsol?
The mesh used for a model geometry plays an instrumental role in how the model is solved, as it determines factors such as: How the geometry is divided. With what shape or element type the geometry is divided. The size, density, and number of elements in the geometry.
What is mapped mesh Comsol?
Mapped. Mapped. Add a Mapped node ( ) to create a structured quadrilateral mesh on boundaries in 3D and domains in 2D. You can control the number, size, and distribution of elements using Size (only the Maximum element size parameter is used) and Distribution subnodes.
How do I create a union in Comsol?
The Form Union is applied when the two objects are overlapping, have continuous mesh and both the objects are fixed. One more thing, you try to check whether you have define all the variables under the parameters which you are using in the simulation.
Is tetrahedral mesh good?
Tetrahedral elements can fit better complex geometry. However, when you integrate the shape functions with points of Gauss it is less accurate than hexahedral elements. In addition, one of the factors that determines the quality of your mesh is the distortion of your elements.
How use swept Mesh in Comsol?
Right-click a 3D Mesh node and select Swept. Choose Remaining to specify swept mesh for remaining, unmeshed domains. Choose Entire geometry to specify swept mesh for the entire geometry. Choose Domain to specify the domains for which you want a swept mesh.
What is mesh size in Comsol?
The mesh element quality is a dimensionless quantity between 0 and 1, where 1 represents a perfectly regular element, in the chosen quality measure, and 0 represents a degenerated element. COMSOL Multiphysics includes the following mesh quality measures:
How do you inspect a mesh in COMSOL Multiphysics?
Inspecting Entities Reported in Warning and Error Nodes To find these geometric entities, we can use the Zoom to Selection button in the Warning node. Toggling off the Mesh Rendering button and toggling on the Wireframe button for 3D meshes lets us easily see the entities reported inside the geometry.
