New Software: DAKOTA toolkit available

Print version Email story Tweet story
Open Source Sandia has released the source code to their optimization toolkit DAKOTA. DAKOTA provides a flexible interface between simulation software and the latest algorithms for optimization, uncertainty quantification, parameter estimation, design of experiments and sensitivity analysis.

Sandia researchers have been developing DAKOTA for about eight years. The initial work focused on optimization methods, but has since branched out into uncertainty quantification and other areas. It has been used internally at Sandia and externally by researchers at Los Alamos and Lawrence Livermore national laboratories in conjunction with DOE’s Accelerated Strategic Computing Initiative (ASCI) program.

News The April issue of Mechanical Engineering Magazine has a feature article on CFD. Stepping Up CFD features a brief interview with CFD researcher and author Milovan Peric and two application stories.

Dr. Peric notes that the increase in available computing power, along with ease-of-use technologies is causing the widespread adoption of CFD in the engineering field.

"Furthermore, CFD tools will become part of a global computer-aided engineering environment, interacting with other design tools to make optimization tasks faster, easier, and more reliable," Peric said.

The application stories feature the optimization of tangentially fired boilers and sand erosion in petroleum pipeline equipment.

Application: EASA helps new burner project

Application

by Frederic Aguile and Alain Quinqueneau, Gaz de France

How do we make our CFX models and results available to our project partners?

That was the critical question when we wrote our proposal for funding under the European Union Brite-Euram programme. In the subsequent project, called MECBURN, a consortium of a gas supplier, burner manufacturers and end users aim to develop a new generation of gas-fired industrial burners. Success depends on close collaboration between modellers and experimentalists to refine the design in the light of a detailed understanding of burner operation at different scales and thermal ratings. So good communication and easy accessibility of the models and their predictions are crucial if the benefits of CFD modelling are going to be realized.
