Temperature in Environments is split into Ambient temperature and Wire temperature.
Wire temperature applies to conductors. Ambient temperature applies to both aerial and ground stays/guys.
Wire temperature for each Environment can be set to one of the following:
Constant - manual input that applies a fixed temperature
Conductor stringing temperature (Stringing) - uses Defined as temperature for each strain section, set in Catenary Definition in Properties panel
Maximum operating temperature (Max op) - uses the Max operating temperature for each strain section seen in Model Properties in Properties panel
The default maximum operating temperature can be updated in Design settings
Ambient temperature for each Environment can be set to one of the following:
Wire - refers to the setting for Wire temperature
When wire temperature is Stringing or Max op, Neara calculates the temperature for objects on a per-pole basis using the minimum temperature of adjacent spans. Note that for poles without conductors, when wire temperature is set to Stringing or Max op, the default values in Design settings will be used
Constant - manual input that applies a fixed temperature
Ambient temperature is used by Finite Element Analysis (FEA) as the length of stays/guys expand and contract depending on temperature which changes the tension in the stay. It is not used in static analysis due to the limitations of the simplified methodology.
Importing Environments with a single temperature field will default Ambient temperature to Wire. See Import and export Environments for more information.
