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:
|
Entity
|
Default Interpolation Points
|
|
open curves, edges, beams, 2D shells
|
endpoints
|
|
shells, 2D plates, 2D solids, faces
|
corners
|
|
surfaces
|
none
|
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.
