Workshop 3.2Meshing ControlWorkshop 3.2 - GoalsUse the various ANSYS Mechanical mesh controls to enhance the mesh for the model below.Problem statement:The model consists of a Parasolid file representing a solenoid.Our goal is to mesh the model using all defaults and inspect the result. Next we will add mesh controls to modify the mesh in various regions of the model.Workshop 3.2 - AssumptionsSince this is a meshing exercise we will not be applying loads or solving the model. Instead we will assume a linear static structural analysis is to follow the meshing operation.Note, due to a certain randomness in the nature of meshing, the actual number of elements generated during the workshop may vary from machine to machine. This is normal.Workshop 3.2 – Project SchematicOpen the Project page.From the “Units” menu verify:Project units are set to “US Customary (lbm, in, s, F, A, lbf, V).“Display Values in Project Units” is checked (on).2.Workshop 3.2 – Project SchematicIn the Toolbox, double click “Static Structural” to create a new analysis system.RMB on the “Geometry” cell and “Import Geometry”. Browse to “Solenoid_Body.x_t”.Double click the “Model” cell to start the Mechanical application.1.3.Workshop 3.2 - Basic MeshingStart by meshing the model using all defaults. This will establish a “base line” from which we can compare changes.Highlight the mesh branch, “RMB Generate Mesh”.4.When mesh generation completes we can view the mesh and inspect the statistics in the details for the mesh branch.4771 elements.. . . Workshop 3.2 – Mesh Size ControlBased on our inspection we may decide a more refined mesh is necessary for our analysis.In the mesh branch details expand the “sizing” section and set the “Relevance Center” to “Medium.RMB the mesh branch and Generate Mesh.5.6.Again visually the refinement is obvious. Details also show an increase in mesh size.10,447 elements.. . . Workshop 3.2 – Mesh Shape ControlA closer look at the mesh seems to show some anomalies where ce
