      <p class="para_topic">You can select one of the following analysis types.</p>
      <div class="title_division">Gaussian</div>
      <p class="para_division">The Gaussian Radius for each checkpoint is indicated by color-coded output according to the Gaussian Radius of curvature for the face at that point.</p>
      <div class="title_division">Maximum, Minimum, Mean</div>
      <p class="para_division">The Maximum, Minimum, Mean Radius analyzes the maximum, minimum, and mean radius of curvature at each point on the face.</p>
      <div class="title_division">Normal</div>
      <p class="para_division">Displays surface curvature in a section plane containing the surface normal and the reference vector at each analysis point. If the vector is parallel to the surface normal, the normal curvature at that point is set to 0. This is useful in analyzing fluid flow across the surface in the direction of the reference vectors.</p>
      <p class="para_division">To select a reference vector, use the Specify Reference Vector option.</p>
      <div class="title_division">Sectional</div>
      <p class="para_division">Displays surface curvature in a section plane parallel to the reference plane. If the reference plane is parallel to the tangent plane at a point, the sectional curvature at that point is set to 0.</p>
      <p class="para_division">To select a reference plane, use the Specify Reference Plane option.</p>
      <div class="title_division">U</div>
      <p class="para_division">The U Radius direction option is available with the Fringe, Hedgehog, and Contour Lines Analysis types.</p>
      <div class="title_division">V</div>
      <p class="para_division">The V Radius direction option is available with the Fringe, Hedgehog, and Contour Lines Analysis types. </p>
