Divide a 2D element into multiple elements using a pattern or entering the number of divisions. If the geometry shape is complex, the shape (quality) of the equal size mesh created by the auto-mesh function may not be good. In this case, use the divide function to increate the Aspect ratio. Set the divide pattern or the number of divisions in the axial direction. Use the [Divide Neighbor Element] option to maintain the node connections with adjacent elements during element division.

Divide by Pattern

Specify the 2D element and pattern. Then, select the reference node.

Pattern -2: Use 1 of the 11 patterns to divide the element outline into 2 segments. The red point that appears in the pattern indicates the position of the reference node. The white points indicate the points that ignore the reference node.

Pattern -3: Use 1 of the 8 patterns to divide the element outline into three segments. The red point that appears in the pattern indicates the position of the reference node.

Divide by Number

Evenly divide the 2D element by the input number of divisions. However, it can only be applied to rectangular elements that are defined in 2 axial directions. Set the number of divisions in the axis 1, 2 direction and define the axial direction as follows. Input the number of divisions in the axial direction of an element edge that has makes up the smallest angle between the specified axis directions.

Axis Direction

[Local Coordinate]

Use axis 1 as the x axis direction of the element coordinate system.

[Coordinate Axis]

Use the coordinate system to specify axis 1. The axis can be select from the Global rectangular system or the Global cylindrical system.

[Location along Vector]

Use the input vector as axis 1. Input the start point and another arbitrary point on axis 1 to create a vector.
