# Heat Flux Point Map

## About this Block

**What it does:** The **Heat Flux Point Map** block generates a Vector Point Map of nodal heat flux from the Thermal Analysis.

**Common uses:**

* Can visualize thermal analysis results.
* The heat flux field can be used to modify geometry to optimize heat transfer.

**Tips:**

* The point map consists of all the nodal points from the Thermal Analysis, and the heat flux values associated with each of those points. These points and values are accessible in the properties of the Point Map.
* The HUD can be used to change the Scale, Weight, Lower bound, Upper bound, color palette and units as required.
* The point map can be exported with the **Export Point Map** block.
