CFD applica...real and computational time relation
 
hi, If we get wing flutter during flight at a spcific flight condition. Can we show the same to happen through the numerical simulation (Time Dependant NS equation solution)? Can we establish some link with the computational time step with the real life time? Cheers? Endee

Re: CFD applica...real and computational time rela
 
If all the quantities of the equations have a real-life dimension, then the computational time is the real time. Another way is to adopt all dimensionless quantities, then after the computation is done you can convert the time step back into the real-life units.
