Temperature

The Temperature class provides a unified interface to create different types of temperature loads and includes nested classes for specific temperature load types.

Nested Classes

---

• Temperature.System: Creates system temperature Loads
• Temperature.Element: Creates element-specific temperature loads
• Temperature.Gradient: Creates temperature gradient loads for beam and plate elements
• Temperature.Nodal: Creates temperature loads applied to specific nodes
• Temperature.BeamSection: Creates temperature loads with cross-sectional variations for beam elements

Methods

---

create

Creates all defined temperature loads (System, Element, Gradient, Nodal, and BeamSection temperatures) in Civil NX.

Temperature.create()

delete

Deletes all temperature loads from both Civil NX and Python.

Temperature.delete()

sync

Synchronizes all temperature loads from Civil NX to Python.

Temperature.sync()
