Interpolation Over Entity
Use the Interpolation Over Entity dialog box to add, preview, or remove interpolation points, and to enter and edit a value for each point. You can use from two to four points to define an interpolation.
The number of points you select depends on whether you are selecting a curve or edge (usually two points) or a surface or face (usually four points).
Creo Simulate selects default interpolation points for some entities as follows:
Default Interpolation Points
open curves, edges, beams, 2D shells
shells, 2D plates, 2D solids, faces
If you want interpolation points that are different from the default points, you can delete the default points and create new ones.
When planning interpolated prescribed temperatures, be aware that:
Each value is a scale factor. Creo Simulate multiplies the Temperature value you specify on the Prescribed Temperature dialog box by the interpolation value at a given location to determine the prescribed temperature vector at that location.
At least one of the points should have a value other than zero.
If you enter interpolation point values before entering the prescribed temperature value on the Prescribed Temperature dialog box, Creo Simulate enters a default value of 1 for Temperature.
The number of interpolation points you select determines the functional form of the interpolation.
