How To Insert A Face Mesh And Mesh Copy In Ansys Workbench?

logo

Skill-Lync

You can copy mesh from one body to another with the Mesh Copy control. For repeating bodies or pieces, this option helps speed up the mesh setup. Performing mesh copy maintains an association with CAD. Only the source anchor body is the scope of the mesh controls. The source anchor body meshes during mesh generation, and the mesh is then duplicated as per the targets.

What is Meshing in ANSYS?

Meshing is the technique of turning irregular shapes into more identifiable volumes called “elements.” Before you begin meshing, you must first upload a geometry or CAD model, to start the simulation process.

Working with the Mesh Module

  • The First step in Working with the Mesh module is to open the module by selecting the type of solver or the component from the toolbox. 
  • After Importing (the solver in the project schematic page), We can access the Mechanical module by double-clicking on the Model. 

  • Once the Mechanical module is open, the mesh settings can be accessed by clicking on the mesh from the project tree or by right-clicking on the mesh for applying the necessary settings.

1.1 Various types of Local Mesh Controls

1.1.1 Face Meshing

The Face Meshing can be inserted for the geometry from the model tree outline by Right-clicking on Mesh→ Insert→ Face Meshing.

The Face meshing can be used to generate a free or mapped mesh on the scoped (Selected) faces. The Face Meshing algorithm automatically determines the number of divisions for the edges on the boundary face. If the number of divisions on the edges is specified using the sizing control, the algorithm attempts to enforce those divisions.

A. Definition

 

  • Mapped Mesh: The Map Mesh drop-down field is used to define if the Generated mesh needs to be mapped to the selection or not. The drop-down field is set to ‘Yes’ for mapping to the selection, If Mapping is set to ‘No’, the Mesher will perform a free mesh and the Constraint Boundary.

    The mapped face meshing is supported for the ‘Sweep’, ‘Patch conforming tetrahedron’, ‘Hex dominant’, ‘Multi Zone’ selection for volume meshing and ‘Quadrilaterals dominant’, ‘Triangles’, ‘Multizone Quad/tria’ selection for Surface Meshing.

  • Method: If the Quadrilaterals are selected for the method, the scoped object (Selected object) will be free-meshed with quad elements. If Triangles are selected for the Method, the scoped object will be free-meshed with all tria elements.

 

  • Internal Number of Divisions: This option allows the user to specify the number of layers of elements that will be generated between the two boundary edges.

    Note:
    * If there is a conflict between the Internal Number of Divisions and a Face sizing control, the mapped face control's Internal Number of Divisions value will take priority.
    * If there is a conflict between the Internal Number of Divisions and the number of divisions on a Sweep mesh method, the Sweep mesh method will return an error notifying the user of the conflict.
  • Constrain Boundary:  The default setting for the Constrain boundary will be ‘No’. If the Constrain boundary is to ‘Yes’, the Mesher will fail if the boundary of the mapped mesh is modified.

1.1.2 Mesh Copy

The Mesh Copy can be inserted for the geometry from the model tree outline by Right-clicking on Mesh→ Insert→ Mesh copy.

  • The Mesh Copy control enables a user to copy mesh from one body to another. This option can be used to reduce the mesh setup time for repetitive bodies/parts. Association to CAD is maintained after performing mesh copy.
  • Mesh controls are scoped only to the source anchor body. When the mesh is generated, the source anchor body has meshed and the mesh is then copied to the targets

  • The source body is the body from which the mesh has to be copied and the target bodies are the bodies which the mesh needs to be copied.

What is Hourglass Effect? Working & Fixes

When the elements in a model deform but the strain energy is not computed for that deformation, it results in an Hourglass deformation effect or Hourglass effect. Usually, this can be clearly seen in the post-processing stage where the elements will have a zig-zag formation.
