Toachieve anoptimal design, aproduct must betreated plete system instead ofdeveloping subsystems independently [2]. MDO has been established asaconvincing concurrent design optimization technique indevelopment plex products [3,4]. Furthermore, ithas been pointed out that, regardless ofdiscipline, basically all analyses require information that has tobeextracted from a geometry model [5]. Hence, according toBow-cutt [1], inorder toenable integrated design analysis and optimization itisofvital importance tobe able tointegrate anautomated parametric geometry generation system into the design framework. The automated geometry generation isakey enabler for so-called geometry-in-the-loop[6] multidisciplinary design frameworks, where the CAD geometries can serve asframework integrators for other engineering tools. Toeliminate noncreative work, methods for creation and automatic generation ofHLCt have been suggested byTarkian [7].The principle ofhigh HLCts issimilar tohigh level primitives(HLP) suggested a and van Tooren [8], with the exception that HLCts are created and utilized inaCAD , the basics ofboth HLP and HLCt can, assuggested byLa a, pared toparametric LEGOV Rblocks containing aset ofdesign and analysis parameters. These are produced and stored inlibraries, giving engineers puter agent the possibility tofirst topologically select the templates and then modify the morphology, meaning the 2 shape,of each template parametrically. 2、Multidisciplinary Design Framework MDO isa“systematic approach todesign space exploration ”[17], the implementation ofwhich allows the designer tomap the interdisciplinary relations that exist inasystem. Inthis work, the
