What does the difference do in COMSOL?
Table of Contents
Difference selections — create selections of entities that are in one selection, but not another. Union selections — combine two or more selections into a single one.
What are the different Boolean operations available in COMSOL Multiphysics?
Boolean selections include:
- Complement Selection — creates selections that are the inverse of one or more selections.
- Difference Selection — creates selections of entities that are in one selection, but not another.
- Union Selection — combines two or more selections into a single one.
What is difference between union and assembly COMSOL?
When using Form Union, the software generates a composite object that consists of connected domains separated by shared boundaries between the neighboring entities. When using Form Assembly, the software instead groups the objects into a single object that contains a collection of disconnected domains.
How do you use intersection in Comsol?
- To create the intersection of geometry objects, in the Geometry toolbar, from the Boolean and Partitions ( ) menu, select Intersection ( ).
- Select the geometry objects that you want to intersect in the Graphics window.
- Click the Active button to toggle between turning ON and OFF the Input objects selections.
How do I make a Rectangle in Comsol?
A rectangle drawn first using the respective shape’s primitive feature, the Rectangle button, and then the Polygon button. Using the Rectangle button, the object is drawn by left-clicking, dragging the mouse to the desired size, and then left-clicking again to complete the drawing.
What is intersection in Comsol?
Intersection. Intersection. To create the intersection of geometry objects, in the Geometry toolbar, from the Boolean and Partitions ( ) menu, select Intersection ( ). You can also right-click the Geometry node to add this node from the Boolean and Partitions submenu.
