      please help, How can i generate heat flux on the square surface (180 mm  by 180 mm) bounded by the equation    Q= q/2(1+cos wt)  has initial condition where q= 1000 w and t = 10s

      The problem with the function you defined is it become infinite at each of those high points.  That is not realistic. 
      Can you develop a modified function that does not include infinity as a periodic value?


      In the plot from my previous post, I used MathCAD where the cos() function takes input in radians.


      In ANSYS Mechanical, the cos() function takes input in degrees therefore there must be a 180/pi = 57.296 conversion factor included.


      Just set the units to SI, add a Heat Flow to the face and change the Magnitude to Function and type in the equation.



      Note that the maximum value on the plot depends on the Number Of Segments as the samples get closer to the values that compute infinity.
