## Synopsis

## Description

elementset generates a list containing element identifiers, name specifying the name of the element set (a string not exceeding 40 characters). The list can then be assigned to i.e. boundary conditions or it can be processed in the post-processor.

Element sets alway store the entries of the list in ascending order. Duplicate entries in the set are not admitted or eliminated. Thus, in contrast to element lists, the position of an entry in an element set has no meaning.

## Attributes

branch br

Specifies the branch number to which subsequently defined element identifiers will be assigned The default branch is 1. br remains active until a new branch number is specified or end is encountered.

elementset id

Copies all element identifiers found in the already defined element set id to the current element set.

elementlist id

Copies all element identifiers found in the already defined element list id to the current element set.

epatch id b

Copies all element identifiers found in the already defined element list of the epatch with identifier id. The b suffix indicates that the epatch body (all elements) are selected.

## Data

list 

Specifies a list of element identifiers of the current branch.

## Examples

Specify the element set 'stringer1' containing a list of element for (default) branch 1:

elementset "stringer1"
1/500
end

Specify the node set 'edge2' containing the set edge1 and additional nodes for (default) branch 1. Add elements 20 to 50 in steps of 10 to the list:

elements edge2
set edge1
elements [20/60/10]
