Create Frequency Study with Solid Mesh Example (C#)
This example shows how to create a frequency study with solid mesh.
//--------------------------------------------------------------------------
// 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 model exists.
// 4. Ensure that the specified material library exists.
// 5. Open the Immediate window.
//
// Postconditions:
// 1. Opens the assembly.
// 2. Specifies the default frequency study results plots.
// 3. Creates a frequency study.
// 4. Applies the same material to all bodies.
// 5. Creates a mesh with default global size and tolerance parameters.
// 6. Sets the number of frequencies.
// 7. Runs the analysis.
// 8. Gets the result frequencies and mass participation factors.
// 9. Inspect the results plots and the Immediate window.
//
// NOTE: Because the model is used elsewhere, do not save any changes.
