<P> </P>
<P>This is achieved by the step 2 in the list I gave: You must set the edge nodes from 2 to 3. Alternatively you could set the face from 4 to 8 or the volume from 8 to 20 nodes. The extra nodes that gambit throws because of this are the midpoints. For Nekton, the recent midside node support feature which fits a parabola through the two corner points and midpoint of the element side is where this comes into play. </P>
<P> </P>
<P>So all you need to do is make sure you have set the mesh nodes as above, and the matlab code does the rest. It separates the element's corner nodes from the midpoint nodes. The midpoint nodes are written into the curved side section of the the REA, whereas the corner points are written into the Mesh data section. So...The matlab code only uses the flag 'm' for curved side data. </P>
<P> </P>
<P>Also, in the inputs section you can specify a maximum radius for consideration. The code will check each edge's corner and midpoints and determine the radius curvature. If it is too large it considers it a straight edge and moves on.</P>
<P> </P>
<P>Hope this helps,</P>
<P> </P>
