Rhetoric Camel: I tried your link and all of the tutorials require some password and login thing to access them. https://www.tutorialized.com/view/tut...a-Fluids/33213 I have tried this tutorial, despite what some of the comments say, it works and no steps are missing and I was pretty pleased with the results. I have been messing around with fluid dynamics for a couple of days now and I suggest you mess around with em to get a feel for what does what, it really helps.
