The prompt
Model a sounding rocket for CFD analysis and FEA analysis with the following parameters: Nose Cone: A von Karman nose (i.e., the Haack series with shape parameter = 0). Length of the nose = 715 mm Radius of the nose = 130 mm Wall thickness = 3 mm Cylindrical Body Tube: length = 1785 mm radius = 130 mm wall thickness = 2 mm Solid Fuel Motor (Mounted inside the body tube): length = 1000 mm radius = 120 mm CD-Nozzle (Mounted at the extreme end of the rocket): inlet diameter = 120 mm (connected to the motor) throat diameter= 3 mm throat length = 1 mm exit diameter = 80 mm convergence and divergence half angles are 30, 45 degrees. do not model the fins, i will model them accordinlgy
