transient inlet profile
1 Attachment(s)
Dear All,

I have a simple question.

How to make transient inlet profile in CFX?

the format of data likes this;(I attached my profile file)

0 <=t <=5sec : 15m/s
5.< t <= 10 sec : 16 m/s
10sec < t <=15 sec : 17 m/s

I did make csv file then impose profile on inlet surface in CFX
In cfx, there is interpolation option so when I look at inlet velocity with time,
the velocity is automatically interpolation with before velocity.

How to put this transient velocity profile on inlet surface without interpolation with before velocity?

I think CEL may be useful but not clear for me.

thank you for any comments on this problem

Best Regards

You should use a 1D interpolation function, not a 3D one for a simple application like this.
