October 26th, 2021 at 14:00 EST – Using fields to create two channel heat exchanger with baffles.

### About this course

This training walks you through how to create a two-channel heat exchanger with fields. While more complex than using the TPMS blocks, fields allow for more control of the heat exchanger design.

**Prerequisites:** [101: nTop Essentials](/lessons/ntop-essentials/overview), [220: Intro to Field Driven Design](/lessons/intro-to-field-driven-design/overview), [321: Intermediate Field Driven Design](/lessons/intermediate-field-driven-design/before-we-begin-intermediate-field-driven-design), [Intro to Two-Channel Heat Exchangers](/lessons/heat-exchanger-design-1-intro-to-two-channel-heat-exchangers/before-we-begin-hex-1)

**What is covered:**

* Understanding the difference between blocks and fields
* Creating a single channel heat exchanger with fields
* How to change the bias and wall thickness of a heat exchanger
* How to add baffles or caps to regions of the HEX Core
