Hi all, I want to model wavy profile given by cosine curve for the microchannel heat sink with rectangular cross section. I have attached the sketch of the geometry. When I use the curve equation feature, then mine cosine curve goes somewhere else and also I am not able to specify its amplitude and period and the orientation as per requirement. Here the hatched portion is microchannel. Please someone help me out with this.
