Manual meshing

Video: Manual meshing

To manually create and modify nodes and elements, use the commands on the Nodes and Elements ribbon bar tab. You can use these commands to:

• Make manual modifications to selected regions of an existing finite element model.

• Build an entire finite element model by creating individual nodes and elements.

Modifying an existing finite element model

Once you have automatically generated an initial mesh on your part, you can use the manual meshing commands to modify individual nodes or elements as necessary. For example, you can use Drag Node to reposition individual nodes within your model to improve aspects of element quality. You can also use commands such as Split Shell to divide selected 2D elements.

Creating a mesh from the bottom up

You can also use the manual meshing commands to create a new finite element model. This method is known as “bottom up” meshing. This technique is useful in cases where the actual geometry is not available or, for example, when you can approximate the geometry using beam elements.

Note:

Nodes and elements that you create manually are not always associated with any geometry. Consequently, the bottom up technique does not offer the automatic remeshing advantages of geometry-based meshing.
