Topology optimization

Stochastics

During the design and development stage of the Product Development (PD) process, the goal is to identify the best design to meet a number of different requirements. This requires the ability to identify the feasible design space, and then to develop the best or optimum design. MSC offers solutions to help address design improvement and optimization through gradient based shape, size and topology techniques for structural component or systems and multi-run techniques to help understand the global behavior of a design, giving confidence that a robust design is delivered.

Obtaining correct loading and boundary conditions for a structural simulation can be challenging. The quality of the result of a simulation is directly related to the quality of the inputs. When it is difficult to obtain good loads and boundary conditions it is often best to rely on other CAE simulations to generate that information. This is where multidiscipline, coupled and chained simulations can both simplify the process of re-using simulation data, and improve the overall simulation fidelity, which in turn improves the quality of and confidence in the simulation. Here are some examples of how MSC’s solutions can improve your simulation capabilities:

• Motion-Structure Integration:predictions by using flexible bodies in a multibody dynamics simulation; vehicle and aircraft frame/structure fatigue, fatigue life of the read/write heads on a computer hard disk drive
• Coupled thermal-structural analysis can give more accurate stress results when accounting for both the thermal loads and the structural loads simultaneously - combined friction and pressure loading of brake disk and rotor
• Fluid-Structure Interaction (FSI)- coupled solution provides more accurate fluid flow simulation when deformed structure is considered, and structure loading is more correctly applied on affected surfaces – tire hydroplaning; airbag deployment; blood flow over an artificial valve
• Chained structural simulations will provide more accurate analysis for example by applying pre-loads/pre-stress before event simulation – aircraft engine blade-out simulation; automotive engine modal analysis

Repeatable process for bottle top load simulation

Simulation portal for managing and tracking simulation processes, history and content

In addition to being able to simulate structural behavior using CAE, many engineers and managers are concerned with making sure the simulation process is repeatable, to ensure high confidence results and enable process improvement, and also that it can be re-done quickly to support design studies and shorten product development time. A side effect of this ability to support higher engineering throughput is that it generates more information that should be tracked and managed. MSC provides next generation solutions for to help capture, author, and manage your CAE processes and content, helping to get the most out of your CAE strategy and investments.
