Load Interpolation
Use the
Load Interpolation dialog box to
add,
preview, or
remove interpolation points, and to enter or edit a value for each point. You can use from two to four interpolation points on the geometry and assign a scale factor to each point.
Creo Simulate selects default interpolation points for some entities, as follows:
Entity

Default Interpolation Points

open curves, edges

endpoints

surfaces

none

If you want different interpolation points than the defaults, you can delete the defaults and create new ones.
When planning interpolated loads, be aware of the following:
• At least one of the points should have a value other than zero. For interpolated loads, you normally use scale factors that lie between 0 and 1. However, you can use larger values if you want to increase the value or vector of the original load through multiplication.
• Each value is a scale factor.
Creo Simulate multiplies the force and moment values (for structural loads) or the
heat transfer rate value (for heat loads) by the interpolation value at a given location to determine the load vector at that location.
• You can define the scale factor as either a positive or negative value. If you use a negative value, you reverse the load direction. Additionally, if you express the load value as a negative number and you use a negative scale value, the signs cancel each other and the load value becomes positive.
• If you enter interpolation points and add scale factors before entering load values, Creo Simulate enters a default value of 1 for FY.
