*CABGEN
Data format:
An arbitrary number of lines with 10 values each, as follows:
NBCAB NEL NELI JO JOI JE JEI IPRO IMAT XLTOT
...
Status:
Optional
Purpose:
To define series of cable elements (3 degrees of freedom per node)
Restriction:
The total number of elements (all types) may not exceed MAXEL. The nodes JO,JE and all the other nodes that will be used as extremities of the generated elements must have been previously defined
Details :
| Parameter | Description |
|---|---|
| NBL | Number of cable elements to be generated |
| NEL | Identification number of the first element |
| NELI | Element number increment |
| JO | Origin node of the first element |
| JOI | Increment on the origin node number |
| JE | End node of the first element |
| JEI | Increment on the end node number |
| IPRO | Index in the table of elementary mechanical and geometrical properties (previously defined by keyword *CABPRO) |
| IMAT | Material index (previously defined by keyword *MAT) |
| XLTOT | The length of each generated element is XLO = XLTOT/NBBEA If XLO=0, the element length is taken from the corresponding properties keyword (referred by IPRO). If XL0 is still null the element length is the initial distance between the nodes composing it. |
Note
The program will generate NBCAB elements with properties IPRO and material IMAT :
El. NEL connecting nodes JO and JE El. NEL+NELI connecting nodes JO+JOI and JE+JEI ... EL. NEL+(NBCAB-1)NELI connecting nodes JO + (NBCAB-1)JOI and JE+(NBCAB-1)*JEI
Example : The example refers to the figure below
*CABGEN
15 1 1 1 1 2 1 1 1
Fifteen cable elements will be generated from element 1, with an increment of one.
Element 1 will start at node 1 and end at node 2. Element 2 will start at node 2 (1+1) and end at node 3 (2+1), Element 3 will start at node 3 (2+1) and end at node 4 (3+1), and so on...
These cable elements will have the mechanical properties previously defined by the index 1 of CABPRO and a material index of 1 previously defined by MAT.
