I have just two boundary conditions along with time dependence. So, velocity_inlet ( air pressure ) takes 2 seconds in a manufacturing process. 2 seconds is working and 2 seconds is stopping time=0 air pressure=0 time=0-2 air pressure=1.5 bar time=2-4 air pressure=0 time=4-6 air pressure =1.5 bar .... ... .... ... Continuing... That is, that is periodical Hot melt glass (other fluid one) acts in the same way, time=0 melt glass temperature =1673.15K time=0-2 melt glass temperature =0 time=2-4 melt glass temperature =1673.15K time=4-6 melt glass temperature =0 and so on, How can I write all above this and how can I compile it to FLUENT. Kind Regards,
