I am simulating flow over vanes and the air flow is from a propeller which the flow velocity varies across the length of the prop. The velocity is zero at the tip then increases to maximum at the center of the propeller before decreasing to zero again towards the propeller core.
My challenge is how to define non constant inlet boundary condition without using UDF.
Can anyone please help me with the know how or material on this.
Someone actually told me it is possible without UDF.
I will really appreciate if I can get this from you
Thanks in advance
It is very easy to define this boundary condition , just write in the txt file the variation of the velocity with the length of the prop .the extence of your file is .Prof and dfter you can upload it : define - profiles -read .thanks
Hi Uchenna,
check the User-Defined Function guide:
