✦ Synopsis

Extensive numerical methods for computing design sensitivity are included in the text for practical application and software development.  The numerical method allows integration of CAD-FEA-DSA software tools, so that design optimization can be carried out using CAD geometric models instead of FEA models.  This capability allows integration of CAD-CAE-CAM so that optimized designs can be manufactured effectively.
