Apply Mesh Control Example (C#)

This example shows how to get and set beams and joints, create a mesh, and apply a mesh control.

//----------------------------------------------------------------------------
// 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. Ensure that the specified part and material library exist.
// 4. Open the Immediate window.
//
// Postconditions:
// 1. Creates a static study named frame.
// 2. Gets beam information.
// 3. Applies Plain Carbon Steel material to all beams.
// 4. Calculates joints for all beams, gets a neutral axis for each beam,
//    and gets the pinball tolerance value and unit.
// 5. Sets the mesher type to alternate curvature based.
// 6. Applies a mesh control and gets its values.
// 7. Creates a mixed mesh and gets its type and state.
//    NOTE: This can take several seconds to complete.
// 8. Inspect the Immediate window.
//
// NOTES:
// *  Beam elements are created by default for parts with structural members.
// *  Because the part is used elsewhere, do not save changes.
