Wall Opening

Define openings in a wall element. By specifying wall opening size and location, wall elements are vertically divided and beam elements are generated at the top and bottom of a opening.

From the Main Menu select Node/Element > Elements > Wall Opening.

Start Node Number

Assign a number to the new starting node created together with new elements in the Model Window. This number is auto-set to the largest node number in use +1. To modify this item, click and select an option to specify a desired number.

Opening Type

Direction: Select a reference point to define opening size and position.

Distance

dx: Horizontal distance from the reference point to the near most edge of an opening

dy: Vertical distance from the reference point to the near most edge of an opening

Opening Size

w: Width of an opening

h: Height of an opening

Subdivide Frame Elements

 If this option is selected, the line elements on the periphery of the wall element are divided according to the opening width.

Merge Duplicate Nodes

Merge overlapping nodes to single nodes if new nodes coincide with existing nodes. Click  to modify the Merging Tolerance.

Note.

Once wall opening is defined, wall element will be vertically divided and additional beam elements are automatically generated at the top and bottom of the opening. If "Auto Constraint for Wall Elements Connectivity" option is checked on in Main Control Data, "Linear Constraint" will be automatically considered for the connectivity with the top and bottom of the connected elements.
