<div class = "body conbody">
<p>Curvature smoothing (<code class = "ph codeph">CURV_SMOOTH</code>) filters the optimization
direction, so that normals in areas with high curvature do not cross,
which results in poor or useless mesh. Default is 5.0, which means the
filter size is 5 times the middle element edge length. In case of mesh
problems try setting this value higher, for example, CURV_SMOOTH = 10.0. </p>

<p> The node smoothing (<code class = "ph codeph">BEAD_NODE_SMOOTH</code>) ensures that
the optimization displacement of neighboring nodes does not become too
great. This is especially an issue near boundaries or active design
variable constraints. Default is <code class = "ph codeph">0.25*BEAD_WIDTH</code>. Values between
<code class = "ph codeph">0.0*BEAD_WIDTH</code> and <code class = "ph codeph">0.5*BEAD_WIDTH</code> (entered as absolute
values in mm) are allowed. </p>
