Access Hole Model [CSB]

The Access Hole Model workflow item is used to define the geometry and finite element model of a bottom flange access hole plate. Access holes are cutouts in the bottom flange plate that provide access for inspection and maintenance.

General

Plate Length: The length of the bottom flange plate.

Plate Width: The width of the bottom flange plate.

Plate Thickness: The thickness of the bottom flange plate.

Plate Material: Assign a material to the plate. Materials can be selected from previously defined options or imported as needed.

Mesh Size: The mesh size specifies the maximum element size for the finite element mesh of the plate.

Mesh Option [MeshAdapt/Automatic/Initial mesh only/Delaunay/Frontal-Delaunay/BAMG/Frontal-Delaunay for Quads/Packing of Parallelograms/Quasi-structured Quad]: Specify the meshing algorithm used for the finite element mesh generation.

Plate Chamfer (Length Direction): The chamfer dimension at each corner of the plate in the length direction. A value of 0 results in a rectangular corner.

Plate Chamfer (Width Direction): The chamfer dimension at each corner of the plate in the width direction. A value of 0 results in a rectangular corner.

Access Holes

Access Holes: Define the access hole cutouts in the plate. Multiple access holes can be added. Each access hole is defined by the following parameters:

• Access Hole Shape [Circle/Rectangle]: Specify the shape of the cutout.

• Hole Diameter: The diameter of the circular cutout. Applicable when the shape is set to "Circle".

• Circle Segment: The number of segments used to approximate the circle. Applicable when the shape is set to "Circle".

• Access Hole Length: The length of the rectangular cutout. Applicable when the shape is set to "Rectangle".

• Access Hole Width: The width of the rectangular cutout. Applicable when the shape is set to "Rectangle".

• Corner Radius: The corner radius for the rectangular cutout. Applicable when the shape is set to "Rectangle".

• Hole Offset X: The offset of the hole center from the plate center in the length direction.

• Hole Offset Y: The offset of the hole center from the plate center in the width direction.
