Elements

The elements section is enclosed in the cards:

    begin: elements;
        ...
    end: elements;

Every element card has the following format:

    <card> ::= <elem_type> : <arglist>
               [ , output , { yes | no } ] ;

where elem_type is one of the following:

• aerodynamic beam
• aerodynamic body
• air properties
• automatic structural
• beam
• bind
• body
• bulk
• couple
• electric
• force
• genel
• gravity
• hydraulic
• joint
• loadable
• rotor
• RTAI output
• Miscellaneous

in case of elements that can be instantiated only once, like the gravity or the air properties elements, the arglist doesn't contain any label; otherwise, a label is expected first, to allow for checks on duplicated elements, namely:

    <arglist> ::= <label> , <normal_arglist>

The data manager reads the element type and the label and checks for duplication. If the element is not defined yet, the proper read function is called, which parses the rest of the card and constructs the element. The elements are read as follows.
