hi,

I am currently working of FSI simulation, I am suppose to implement the changing boundary conditions periodically i.e. as shown in the picture attached here.

I have written a scheme file and trying to implement the changing boundary conditions but, unfortunately it is not working as I want.

What kind of operators can I use in the place of >/< i.e. for something as 0.0375<t<0.0625 because BCs should change in that range (when flow-time falls in that range).

show your code

best regards
