Add Nonuniform Force Distribution Example (C#)

This example shows how to add a force of nonuniform distribution to a study.

NOTE: To get persistent reference identifiers (PIDs) for model selections, you can use pidcollector.exe or IModelDocExtension::GetPersistReference3.

//--------------------------------------------------------------------------- 
// Preconditions: 
// 1. Add the SOLIDWORKS Simulation as an add-in (in SOLIDWORKS, click 
//    Tools > Add-ins > SOLIDWORKS Simulation > OK).

// 2. Add the SOLIDWORKS Simulation primary interop assembly as a reference
//    (in the IDE, click Project > Add Reference > .NET > 
//    SolidWorks.Interop.cosworks > OK).

// 3. Verify that the assembly exists. 
// 4. Open the Immediate window.

// 
// Postconditions: 
// 1. Opens the assembly.
// 2. Inserts a coordinate system.
// 3. Gets the Ready study.
// 4. Adds a force of nonuniform distribution to Ready.
// 5. Inspect the Immediate window.
// 
// NOTE: Because this assembly document is used elsewhere, do not save changes.
