Estimating the Effect of Large Design Changes on Previously Computed Engineering Simulation Results


Krishnan Suresh, Sankara Hari Gopalakrishnan

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing an efficient software modeling tool for prototype testing.
OVERVIEWVirtual testing of a 3-D solid model is a time consuming part of product design before manufacturing. Engineers often use a software modeling tool called Finite Element Analysis (FEA) to speed up the process. A grid of nodes—called a mesh—that represent important features provides a representation of the product for virtual testing. However, any design changes that are incorporated require the entire mesh to be recreated.
THE INVENTIONUW-Madison researchers have developed a method for modeling products that does not require re-meshing. Previous simulation results are used to estimate the effect of design changes. The result is a swift but accurate estimation of design changes on product performance.
  • Analysis of stress, buckling, thermal change, fatigue, fluid dynamics, simulated motion and vibration
  • Provides an efficient software modeling tool for prototype testing
  • Allows users to test multiple design solutions in parallel
  • Design changes may be analyzed without repeating entire analysis
  • More widely applicable than current FEA methods
  • Applies adjoint theory
  • Allows exploration of many alternative designs
  • Bypasses re-meshing
  • Can provide cost estimation for machined parts
