2. Fluorem © 2007. All rights reserved CAD CFD Final solution 1 unique solution N itérations for 1 configuration Time, money, resources Each configuration is a new CFD run! Sequential iterations => means weak cycling SOLUTIONS Often 2D => means simplification of flow => real optimization ? Expertise => need choices => all possible configurations ? Classical design process => integration impossible in industrial process design!

3. Fluorem © 2007. All rights reserved Infinity of solutions CAD Turb’Opty database CFD Design, Optimisation, Other physics 1 single iteration for N configurations ! The idea : construction of a CFD database included in the domain of the whole configurations ! Post User profile : CFD expert User profile : designer non linear variations according to parameters real time access all admissible solutions, no a priori choice one single run, one unique mesh
