This becomes possible due to the use of the potential of modern parallel computing technologies based on supercomputers of cluster architecture, and the use of numerical optimization methods. The first step is to create a 3D object model using CAD system. Ariflow simulation itself is a complex engineering task due to flexibility of an object. The second step will be an iterative calculation of the shape of the object under an aerodynamic load. For this purpose, the calculation of the aerodynamic forces acting on the structure will be carried out by means of finite element method. Then the calculation of (elastic) structural deformation is carried out and corresponding corrections are made to the parameters of the model and calculation of aerodynamic forces is repeated. At this stage, considering the estimated complexity of the problem, supercomputers of cluster architecture should be involved. The third step will be optimization of aerodynamic properties. Also visualization of the results in the space of parameters will give a visual desicion making aid for selection of pareto-optimal solutions.5481 Product Description popup.authors Роганов В'ячеслав Юрійович popup.nrat_date 2020-04-02 Close
