Editor’s Pick of the Week—December 20, 2006 Common Data Model Unites CAE and MCAD Tools CoMeT lets you leverage a true common data model for dynamic, bidirectional simulations independent of CAD and CAE.Comet Solutions, Inc. (Albuquerque, NM) recently launched its firstproduct, CoMeT/SD —  CoMeT/StructuralDynamics. CoMeT/SD is part of aplanned suite of applications for simulation-driven engineeringapplications bearing the CoMeT imprint. CoMeT — Computational ModelingToolkit — is the result of work first begun by Malcolm Panthaki and Dr.Walter Gerstle at the Center for High Performance Computing at theUniversity of New Mexico in Albuquerque.CoMeT creates a work environment for the simulation-driven engineeringof complex assemblies. CoMeT is intended to help you get more work outof your analysis tools and CAD systems by facilitating the capture ofproduct knowledge, the creation and automation of processes, and theleveraging off simulation results to drive your CAD models.    With CoMeT/SD, you can work in a single environment to build a solid model in your MCAD system (left), andthen use that geometry for subsequent analysis (right) without having to re-create your design. Click images to enlarge.The single, coherent environment enabled by CoMeT begins by creating acommon data model, called CoMeT’s Univeral Engineering Model or UME for short. What UME means for you is that point-to-pointtranslations between disparate CAE tools are eliminated. Because ofthis, CoMeT establishes inherent bidirectional associativity betweenformerly discrete MCAD and CAE data from a variety of vendors. Forexample, CoMeT/SD enables you to take a model created in say, Pro/E andsimulate the performance of structures and mechanisms (both static anddynamic) using codes such as ADAMS for rigid and flexible multibodydynamic simulations and ABAQUS, ANSYS, and MSC.NASTRAN for FEA (finiteelement analysis). Using bidirectional associativity between MCAD andCAE data, CoMeT allows engineers to modify geometric parametersautomatically during design space exploration.CoMeT’s abstract modeling capabilities are said to significantly reducethe amount of engineering data entry and reentry, even across hugechanges to the MCAD design. The abstract model specification, says thecompany, also allows non-experts to easily perform complex analyseswithout deviating from the specified process.Comet lets you define multiple engineering analysis tasks for yourmodels. You can reuse previously defined tasks by adding them to yourmodel, and CoMet’s process and task interfaces give you a complete andtraceable view of the models, the simulation processes to be run onthem, and the analysis results—all in one place.You can also run simulations iteratively to explore the design spaceand find optimized product designs. Each process will simulate variousphysical phenomena using multiple CAE codes. Analysis results areautomatically organized, facilitating results examination andcomparison. Additionally, you can use CoMet/SD to author simulationtemplates.CoMeT/StructuralDynamics is available for immediate use. CoMeTSolutions also offers complementary services for product adoption andengineering process implementation.
