Prescribed Temperature Conditions
Use Home > Prescribed Temperature in Thermal and FEM mode Thermal to define a temperature boundary condition for one or more geometric or model entities. A prescribed temperature is a thermal boundary condition that limits the temperature of your model. See Guidelines for Thermal Boundary Conditions and Guidelines for Thermal Boundary Conditions for Geometry.
When you click Home > Prescribed Temperature, the Prescribed Temperature dialog box opens. The dialog box has the following fields:
• Name—The name of the boundary condition.
• Member of Set—The name of the boundary condition set. You can select an existing boundary condition set from the drop-down list, or create a new set by clicking New to display the BC Set Definition dialog box.
• References—The list includes the following geometric entities. You can select the geometry for these references before or after you open the Prescribed Temperature dialog box.
◦ Surfaces—one or more individual surfaces, part boundaries, intent surfaces or surface sets.
◦ Edges/Curves—edges, curves, composite curves or intent chains and intent curves.
◦ Points—one or more points, vertices, point features, patterns of points or intent points.
• Temperature—Specify values for a prescribed temperature as follows:
◦ Value—Type any real number for the prescribed temperature, arithmetic expression, or Creo Parametric parameter. For points and vertices, you can assign only a uniform temperature.
◦ Advanced—Expands the dialog box to display the Spatial Variation drop-down list. For edges, curves, surfaces, 2D plates, and 2D solids, you can assign a spatially varying prescribed temperature.
You can select units for prescribed temperature from the drop-down list adjacent to Value or accept the default units.
• Preview—Adds a series of arrows to your model showing the location and distribution of the prescribed temperature condition.
After you accept the values in dialog box, the software places a prescribed temperature icon at each location you selected.
