sd or simdesigner is a softwar for catia
SimDesigner makes linear and nonlinear FEA, thermal analysis, and motion analysis capabilities from MSC Nastran, Marc, and Adams available within the CATIA V5 CAD environment. Many manufacturers want to bring simulation forward in their product development process to have functional performance analysis lead design, rather than simply validate design. This can be challenging in organizations that cling to an “over the wall” mentality between design and analysis engineers, as CAE engineers wait for detailed drawings to get started on even the most basic analysis, and in turn, design engineers wait for CAE to be completed. Worse yet, changes made late in the design cycle can increase costs by several orders of magnitude and significantly delay time-to-market.
