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.
