There's plenty of info if you google it. The HFSS manual even has an example of microstrip transmission lines. You will just need to adapt it to your coplanar strip line.

There are numerous responses to this question on this site. One or two of the individuals have even used the transmission line format. You might look into Simon or Waddel's books on transmission lines as well. I also like Moreno and Southworth.
Frankly speaking you don't need a high end 3-D tool like HFSS to design a transmission line. A better choice is to try a dedicated transmission line EM simulator. I would suggest using **broken link removed**, which can give you broadband solutions in a few seconds to at most one minute.
