Automatic

The colors will automatically be distributed according to the minimum and maximum heat flux which appear in the construction.

User defined

This option allows you to define the minimum and maximum values yourself (i.e. to be able to compare heat flux field results across different variations). Values greater than the maximum defined value will take on the color of the maximum value. Values smaller than the minimum will take on the color of the minimum value.

Same color for each

Determines whether values (heat flux) within a certain range should have the same color, or not, in which case a color gradient of the values is generated. If this option is selected, you can also define the range with the same color.
