While it's possible to define and use a constant temperature for conductors in a project - for example using 100°C across a design - Neara offers the flexibility to define per-strain section maximum operating temperatures associated with different Environments.
This is useful in a project that has a mix of lines in the design.
Approach
When configuring maximum operating temperatures on strain sections, the following steps are required. Each is described in detail below:
Set the project's Default Max Operating Temperature. This will apply to all new strain sections created in the project, and to all strain sections that do not have their Max Operating Temperature overridden.
Where required, Override the Default Max Operating Temperature for individual or multiple strain sections in the design.
Set Wire temperature in one or more Environments to use Max Operating Temperatures. By default, Environments use a Constant wire temperature set in the Environment's configuration, across all conductors in the design.
Temperature units
The Maximum Operating Temperature is defined in °C or °F, depending on the units of measure set in the Project Settings.
Set the project's Default Max Operating Temperature
Select Project menu / Design Settings:
On the popup, enter a new value in the Default Max Operating Temperature box:
The updated value will apply to all new strain sections, and to all strain sections that do not have their Override max operating temperature checkbox checked
Override default Max Operating Temperatures for strain sections
Override a single strain section
The Maximum Operating Temperature of a conductor is defined per strain section.
Click the Move & Select tool on the toolbar, and then select a strain section in the Perspective, Schematic, Plan or Profile view.
Place a checkmark in Override next to Max Operating Temperature in the Properties tab, and enter a new Maximum Operating Temperature:
Override multiple strain sections
You can update the Maximum Operating Temperature for multiple strain sections quickly by using the bulk editing features in a StrainSections report.
Click the (+) to the right of any group of tabs, and select Custom Report on the popup:
When prompted, select StrainSections as the datasource of the report, give it a suitable Report name, and click Create:
The report will be displayed. You might find it convenient to re-arrange the workspace so that the report and Perspective (or other) view are both visible:
Filter the report to just those strain sections that match your criteria with the filter icon in the column headers. For example, you might filter the report to only show rows for strain sections of a particular Type:
Option 1: Update the strain sections row-by-row
Scroll across and place a checkmark in the Override Max Operating Temp column, and change the Max Operating Temperature value, for each row that you want to update:
The updated values are saved automatically
Option 2: Bulk edit all visible rows
If you have a large number of strain sections to update, use the Bulk Edit Column feature.
Select the Bulk Edit Column icon in the Override Max Operating Temp column header, and in the pop-out place a checkmark in the checkbox. This will automatically set every visible row to have that checkbox turned ON:
Click outside the pop-out to dismiss it.
Next, select the Bulk Edit Column icon in the Max Operating Temperature column header, and in the pop-out enter the new Max Operating Temperature value in the box:
Click outside the pop-out to dismiss it.
All visible rows are automatically updated:
Set Environments to use Max Operating Temperatures
By default Environments use a Constant wire temperature set in the Environment's configuration, for all conductors in the design.
An Environment that has a Constant wire temperature set will ignore the project default Max Operating Temperature value (and any overridden Max Operating Temperature values set on specific strain sections) for any analysis based on that Environment.
Select the Environments menu. The current setting is shown in the Wire Temp column for each Environment:
The Wire Temp column will display and use °C or °F, depending on the units of measure set in the Project Settings
In the drop-down on this screen, "C" is an abbreviation for Constant, not degrees Celsius
Change the Wire Temp column to use M - Use conductor max operating temperatures for the relevant Environments in your project:
