<p>Is it as hard as people say it is? Is there material from other classes that would be useful to review?</p>
<p>Nah, it flows naturally from one part to the next.</p>
<p>^ well done. Aren’t the Navier-Stokes equations used in CFD? They were one of the millennium prize problems in math and I don’t think they’ve been fully solved yet. I bring that up not because you’ll have to solve nonlinear partial differential equations, but considering the techniques and computing power required to model that stuff, I’m guessing it is a hard class.</p>
<p>I’ve been learning how to create temperature and fluid models for fun this summer with C code, and let me tell you, it’s insanely hard. Not sure if such a class would be math based or programming+math based, but the even the math is hard by itself. In the past 2 months, I’ve had to learn matrices and matrix solvers(Gaussian elimination and TDMA), nonlinear PDEs, implicit/explicit methods, and tons of other stuff.</p>
