Incorporating variability in simulation models

As a complementary CAE software when used in conjunction with a design simulation package, RAMDO provides a more reliable product design. It allows the designer to take into account the variability of design inputs (materials, loads, operating conditions, etc.) and create an optimised solution.  RAMDO performs this analysis with efficient use of computer resources, a user-friendly interface, and at a cost-effective license subscription.

“We are excited to be joining the Altair Partner Alliance,” said Nicholas Gaul, COO and Lead Developer at RAMDO Solutions. “RAMDO can be a great tool for HyperWorks users to explore design reliability improvements by the formal inclusion of variability (materials, loads, manufacturing, operational conditions) into simulations. Our software increases the reliability and robustness of designs at reduced total product lifecycle costs, thus ultimately creating better products and happier end customers.”

Companies using design simulation software can benefit from adding RAMDO to their workflows. In the aerospace industry, RAMDO can be of particular interest in the design of wings, engines, and interiors by taking into account the variability of materials, aerodynamic loads, electrical resistance, manufacturing, and operating conditions. In the architecture, engineering, and construction industry, RAMDO can help structural designers take into account variability of structural and wind loads, material properties for steel, concrete, soil, and fluid flows for thermal distribution and solar loading.

The primary goal of this product is twofold. First, it provides users with a tool to help them understand how variability affects their application. Second, it guides designers into improving the reliability of their design for products and systems. An intermediate benefit of this tool is also a reduction of computational times for UQ, reliability analysis, and RBDO. The result for end consumers is a product that usually includes reduced weight, lower costs, less frequent maintenance, as well as improved safety.

“Structural optimisation is used as part of many standard design processes to create better-performing products at lower costs. However, it is important to note that an optimised design could be at the edge of feasibility when considering potential variations due to manufacturing, and operational environment,”explained Fatma Kocer, Altair’s VP of Business Development - Design Exploration. “When this risk is significant, a safety factors approach can be employed, but this approach can lead to overdesigned products.  We are happy to have RAMDO in the APA program with solutions for complex problems of reliability and robustness-based design optimisation.”

Anintroductory webinar for RAMDO will be held on 15^th February at 10 am. For more information about the software, please visit here.
