I make the design of spring in solid works. I begin the study in solid works simulation by some steps
1- I choose the type of study as static study
2- I add the Material of the model as Alloy steel
3- I add the Fixture as Fixed Geometry, Reference Geometry
4- I use the load as Force
5- I make the mesh by choosing a stable mesh between fine and coarse mesh
6- Run study and I show the result
