<p>The height of the bead stiffeners is formulated as a constraint of
the controller-based optimization problem. The bead height is initially
zero for all nodes and the optimizer moves the nodes in the shell normal
direction until they reach the bead height. </p>
<p>The bead height is defined by the <code class = "ph codeph">DRESP</code> command
which is then referenced in the <code class = "ph codeph">CONSTRAINT</code> command.
A typical bead height constraint could be defined as follows:</p>
<pre class = "codeblock">
<code class = "ph codeph">
DRESP
 ID_NAME    = dresp_bead_height
 DEF_TYPE   = SYSTEM
 ND_GROUP   = design_nodes
 TYPE       = BEAD_HEIGHT
 GROUP_OPER = MAX
END_
  
CONSTRAINT
 ID_NAME   = bead_height
 DRESP     = dresp_bead_height
 MAGNITUDE = ABS
 EQ_VALUE  = 10.
END_
</code>
