Hi everyone,

I am newbie in UDF function, then I have a question want to ask you.
If possible, could you please help me or explain to me the method to do.

I have two tanks with different presssure connected via pipe with valve. Valve will be opened following physical time as the attached image.
Now, I want to simulate the flow field in hole system.
I understand that I need to create UDF function for valve opening, however, I lack of experience in this step.
Could someone give me a help.

I thank you very much
