Hi, I copied this attachment from one of Nur Kholish Majid discussions. I tried replying to the post, but for some reason it wouldn't post. I was wondering if anyone knows if this was done in SolidWorks or is another software needed to create an animation as this one. I'm very interested in learning how to simulate air flow with moving arrows just as it is showing in Majid's animation. Maybe someone can let me know where I can get more information on this subject, thank you.
