problem in writing CEL expressions for mesh motion

hello,

I am quite new in CFX . I need to get mesh deformed at boundaries using specified displacement mesh motion and thinking to input x and y components of displacement as CEL expression . my original equation is kind of fourier function and for example the x directional motion equation is x= 20.11+ 8.569 cos 7.854t+3.256 cos 7.854t+.....so on ...can anybody give me instruction that how to write this quation as expression correctly in boundary mesh motion specified displacement . I was trying to write it like xGlobal [mm] = 20.11[mm] + 8.596 [mm] *cos( 7.854 [radian s^-1] * t [s])+........so on.. but it gave error that suucessfully read 13 characters xGlobal [mm] then error detected at 20.11[mm] + 8.596 [mm] *cos( 7.854 [radian s^-1] * t [s])+... can anybody suggest how to write it correctly ... the motion is time dependent................ thanx for reading
