Triangular Load in Creo Simulate

Most of this information is in the CREO simulate help documentation under the topic spatial distribution.

If you choose "Total Load" it means the weighting and does not effect the total.  In my interpolation example the 0.2 weight locations would have loads 20% of the 1.0 weight locations.  If it was a ramp load from zero then the 0.2 weights/values would be changed to 0.0

This is also true for function by CSY, that it is a weighting as well.  In my example the geometry at zero X value for the CSY will have zero weighting or start at zero load, but I could have moved the CSY or changed the function to start at 0.2 as well.  The preview and the icon generated give a good idea of what the distribution will look like so you can change values or the function too see the effect on the load distribution.

The integral of the distributed load will equal the total load magnitude, regardless of the relative distribution.  In other words the equivalent point load of the distribution will have the magnitude and direction entered regardless of the function used or the "values" on the interpolation points, the only thing that might change is the location of the equivalent load.  For uniform vs. ramped from zero, the equivalent load location moves from the center of the loaded area to 2/3 of the "total distribution length" from the zero end.

For the types other than "Total Load" the final values are a multiplication of the Load Value and the weighting/distribution function.

To round out this discussion, the pressure load type also allows an external file for the distribution.

For example the pressure field found from a CFD analysis can be "projected" onto a model.
