Splitting 1D elements

You can use the Split 1D Element command to subdivide selected 1D elements, such as beam, rod, or bar elements, into two or more elements of equal length. The new elements created by the Split 1D Element command retain all of the material and physical properties of the element or elements that you are subdividing.

The following graphic shows how the Split 1D Element command can be used to subdivide multiple 1D elements along the rungs of a simple ladder model. (1) shows the existing 1D elements along the rugs. There are 4 elements on each rung. (2) shows the resulting mesh after the Split 1D Element command was used to subdivide each selected element into two smaller elements so that there are 8 elements on each rung.

Splitting elements by number of length

In the Split 1D Element dialog box, you can use the Split By list to control whether to split the element:

• Into a specified number of smaller elements.

• Into smaller elements of a specified length.

If you specify the desired length of the smaller element, the software uses that length as a guide to split the element into small elements of equal length. However, in the exact length of the smaller elements may not exactly match the length you specify.

For example, if the length of the element to be split is 14mm, and you specify a length of 3mm, the software splits the element into 5 smaller elements (14/3 = 4.67), each with a length of 2.8mm (14/5 = 2.8). If you specified a length of 6mm, the software splits the element into 2 smaller elements (14/6 = 2.33), each with a length of 7mm (14/2 = 7).
