definining an oscillating geometry

Please login with a confirmed email address before reporting spam

hi,
i am working on simulation of flow around an oscillating cylinder.
Can you help me out in defining the function for oscillation and in what format the function should be put at the required place?

for example for integration we can put some variable a= mod1.intop1(yx)
I am not able to get how to define the ocsillatory function in such way.

Thank you
Hemant
