Part 3: Mesh and assign material properties to Guitar string
Step 05: Create the Mesh
•Select the 1D Mesh 
tool in the Mesh group of the Home tab tool ribbon
•Select the line
•Ensure that Type is set to CBEAM
•Set Mesh Density by to Size
•Set Element Size to 5mm
•Click OK
Step 06: Assign Materials and Properties
Step 06: Assign Materials and Properties
•Expand the 1D Collectors item in the Simulation Navigator
• Right-click on the Beam Collector(1) item and select Edit
•In the Mesh Collector menu that appears, click on Edit
•Click on the Show Section Manager 
button for Fore Section
•In the Beam Section Manager menu select Create Section
•Ensure that the Beam Section is a ROD and enter 0.2413mm for DIM1
•Click OK and then Close
•Click on the Choose Material 
button for Material
•Select AISI_Steel_4340 from the list that appears then click OK
•Click OK twice
