UDF for Piston movement
 

Hello to All, I am new to this group.Presently I am trying to write udf for the piston movement.It should move with respect to time only and the cycle should be completed in 4 min.How to declare the time(for piston movement) to the fluent........Thanks in advance! Regards, Harish.

Hai....

I am not getting the equation for which the piston moves.Here it is an open cylinder and the piston movement should be controlled by the differntial pressure between the sides of the cylinder.So if anyone has worked in related to this area,please provide me the guidelines.

Regards, Harish.
