Hi Farnia,
May I know which packages you downloaded? Also which licenses are included in Ansys academic version for you?
Can you go to the toolbox option --> component systems and check-in toolbox customization (view --> toolbox customization) if you have ICEM-CFD in it? If yes, then can you please check that option
Maybe this link can help https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v232/en/wb2_help/wb2h_IcemCFD.html?q=ICEM
