Connect intersecting triangular and quadrilaaterial 2D elements.
Several components\elements can be connected simultaneously. Components defined as
master entities will be preserved. It is suggested that you ensure that 2D elements
are properly intersecting.
From the menu bar, click Mesh > Boolean Operation.
The Boolean Operation dialog opens.
Choose the type of boolean operation to perform.
Choose Union. Figure 1. Union
Choose Subtract. Figure 2. Subtract
Use the All entities to Boolean selector to select all components or elements
that will be involved in the boolean operation.
Entities defined that are not present in master entities to preserve are
considered as slaves. If you define all entities for boolean as master
entities to preserve, entities will intersect and connect components but
will not remove any internal shells. The boolean operation will only remove
internal shells if they are enclosed and if they belong to an entity not
defined as master entities to preserve. If both of these conditions are not
satisfied the internal shells will not be removed.
Use the Master entities to preserve selector to select components that you do
not want to remove internal shells for.
If you have components with open shells but they are connected to other
components and create closed shells together, select the Consider
connected components as one shell checkbox to consider the
closeness of the connected shells while deciding which internal shells will be
removed.
To create connection edges, select the Keep intersect
edges checkbox.
To remesh elements near the intersection of inputs based on the defined
parameters, select the Local remesh at contacts
checkbox.
In a case of tria element input, tria elements of first order will be
remeshed. In a case of quad elements input, remeshing will be done with mixed
elements.
In the Number of layers field, enter the number of additional layers next to
the intersect edge to remesh.
In the Feature angle field, enter the feature angle to use for the remeshed
elements to be captured.
In the Growth rate field, enter a growth rate to use for remeshing.
