Modelling a heat sink with COMSOL

Hi,

I'd like to model a certain Aavid heat sink that has a profile that can be seen in the picture I'll attach. I'm new to Comsol so I don't have much experience with creating objects of certain profile. I'd know how to create a heat sink with normal fins but this one is a little bit tricky for me as it has a bit inclined and curved fins. I also considered doing the profile in Solidworks and importing it to Comsol, but I'd like to stick to Comsol for the moment.

Thanks!
