For more comfortable work to avoid some iteration ‘by hand’ there are some features build in the KULI advanced module like •Parameter variation (what if scenarios) •Automatically optimization by defining optimization targets and optimization parameters KULI is a 1D-Tool, providing interfaces to integrate the results out of 3D-CFD calculations •Consideration of non-uniform air flow distribution •Coupling with CFD codes (co-simulation) •A further advantage of KULI is that the user has the possibility to couple KULI with other software-tools, for example to include simulation models for the control unit of a fan or other electrical components. At least the user has the possibility to couple with other Software-Tools, for example if one has programmed the control unit of a fan or other electrical component with an external program. •Interface to external programs, e.g.◦by COM technology ◦with direct access ◦to Matlab/Simulink
