The objective of this course is to prepare your part for simulation and printing. After completion, you will have learned to run an analysis of your HEX design in Ansys Fluent and Ansys Discovery, as well as how to iterate through designs based on these results.

**Prerequisites:** [101: nTop Essentials](/lessons/ntop-essentials/overview), [102: Guide to Meshing](/lessons/intro-to-meshing/before-we-begin-meshing), [210: Intro to Latticing](/lessons/intro-to-lattices/overview), [220: Intro to Field Driven Design](/lessons/intro-to-field-driven-design/overview), [HEX Design Part 1: Intro to Two-Channel Heat Exchangers in nTop](/lessons/heat-exchanger-design-1-intro-to-two-channel-heat-exchangers/before-we-begin-hex-1), [HEX Design Part 2: Heat Exchanger Flow Distribution and Control](/lessons/heat-exchanger-design-2-heat-exchanger-flow-distribution-and-control/overview)

**What will be covered:**

* Meshing techniques (for analysis and manufacturing)
* Interoperability
  * Ansys Discovery
  * Ansys Fluent
