Respected sir/madam/friends/
I am running a VOF simulation .
I have to run the same boundary conditions for some timestep, then i have to change the boundary conditions for remaining simulation in fluent.
how to do this?
please help me out...
Dear Raju,
According to me and by definition, boundary conditions do not change during a step (or steps) of for example a time series. That's why they are boundary conditions in the first place. If they change you assume that the bio-geophysics of the processes determining your time series, change their nature (definition) as well. I guess in that case you need another approach (mathematical model) in the new case. If a Fourier series fits a certain proces time series well, its (mathematical) boundary conditions stay valid for the complete time series. If you see a bad fit from a certain timestep. I think, you need another temporel series model (polynomial, probabilistic math time series models etcetera...).
Cheers,
Frank
Thank you sir
I will try to do this method.
Actually I did by another method sir
