I need to simulate a pressure impulse at inlet boundary condition:
for t<=0.01 I need:
and for t>0.1
where Pmax and w are known.
Please help to write it using CFX expressions.

In CFX V13 you can use if statements in CEL so this is easy. In previous versions you need to use the step function - still easy, but a bit weird. For instance Pin=step(t-0.01[s])*Pmax*(sin(w*t)^2) should do it.
I note your function is undefined for 0.01<t<0.1. I assume that is a typo.
