moving wall problem

[moloy_kb]

Dear all,
I want to simulate the flow through a pipe in Fluent whose wall is moving in sinusoidal manner along normal direction. Please help me in this regard. I am also attaching the geometry of the problem.

See the tutorial in the PDF attached. You will need to make a UDF for this purpose as well.

Hi William,

I have also been trying to simulate a similar problem as the case in the PDF file which you have uploaded. However, I am having problems in getting the UDF right for the example. Can you please post the code for the UDF as a reference for the case? It would be very helpful.

Thanks in advance.

Dear William;

I am trying to solve a similar problem and I have problems with the UDF file. Can you send me the UDF code too. My e-mail adress is "ivuruskan@gmail.com".

Thanks a lot

hello guys
I am new to fluent so please be gentle with me 

I am also trying to simulate moving objects in a chamber. It is hard for me to understand UDFs (was looking around the internet for a while without finding REAL tutorial).
Can i define a moving wall without UDF? a practical (even very simple one ) example might be very helpful

thanks a lot
