CFD FASTRAN
 
i executed supersonics simulations in CFD FASTRAN of ogive cylinder to obtain axial,normal and moment coefficients but the axial coefficient donīt converge i have a large error and normal and moments coefficients my error is less than 2 %, Someone could help me???

Re: CFD FASTRAN
 
1)is your model axi-symmetric? 2) What is the flow Mach number? 3)What boundary conditions have you given?

1..- yes, it is axi-symmetric, 2.- The Mach number 2.5. 3.- i executed all external boundary inflow-outflow and also with inlet and outlet boundary in both cases the results they are the same

Thanks
