Can I use a field to apply different loads to different curves?

I have a surface with an array of edges that I wish to load with different forces. The forces differ in magnitude only. I have created curves on the various edges to be loaded, the curve IDs are 1-30. What I want to do is apply a load of say 10 lb to curve ID #1, a load of say 12 lb to curve ID #2, and so on. I can easily create a table that spells this all out (column 1 could be Curve ID #, column 2 could be force magnitude). How and can I use a Field to do this?

A field can describe data that varies in a variety of ways this includes as a function of distance along a geometric curve (create/spatial/PCL function with coordinate system=Parametric) or that varies as a function of FE ID (create/spatial/FEM and input a table of id/value pairs. But you can not do the combination which I think you want, a table of Geometric id/value.

To use such a table you would need to create a PCL function to automate the creation of multiple LBCs reading your table as input. This may be simple for a specific case where the scope is limited. Maybe if you share the PCL calls that an example LBC makes(from the session file) for one of the curves then suggestions can be made how to write the PCL to read a file(table of ID / value pairs) and issue multiple LBC calls.

best regards

Thanks Arthur. Gret info to chew on. I think for my immediate case and need, I'll just create the 30 different loads individually. I'll keep working on this though because I can conceive of situations that would go beyond my patience to input or change/iterate such loads manually.
