Computational fluid dynamics is a technology that evaluates liquid and gas flow within a design. While technology like this has traditionally been left to analysts, recently, more and more design engineers are using it to help guide early design decisions.
Of course, as a design engineer, you might be asking how much time you’ll lose running your own simulations. After all, you have deadlines to meet. That’s one reason we added a wizard in Creo Flow Analysis. The interactive tool steps you through your options, so you can predict fluid flow (internal or external) quickly and easily.
