Hard Points Mesh Control

Introduction

This option is used to create nodes at the specified point location on the body/face/edge during meshing.

Hard Points can be defined by:

  1. Selecting a point on the face/edges.
  2. In case of meshed body we can select nodes as hard point.

  3. Using CSV file with the XYZ co-ordinates.

    Sample CSV file format,

Hard points for body can be defined using nodes (existing nodes and orphan nodes) and CSV File. In order to apply hard points for CAD bodies, we need to create the orphan nodes on the desired locations. The hard points can be ON the CAD surface or inside the CAD body. Those points that are on the surface will be respected during surface mesh and hard points inside the bodies will be respected during volume mesh. The same applies to FE bodies.

Limitation

Supported only for Tri3/Tri6 and Tet4/Tet10 meshing.

Note: For Body based hard points after volume meshing, if environmental variable SL_CREATE_SETS_FROM_HARDPOINTS=TRUE is set, the hard nodes will be created as Sets and Node Groups with same name as the mesh control name. Similarly, if environmental variable SL_CREATE_NODE_GROUPS_FOR_HARDPOINTS=TRUE is set, after volume meshing the hard nodes will be created as Node Groups.

Example

Hard points are applied on a face.

Nodes are created at the specified points.

For scripting,if CSV file path is defined,hard points are created based on XYZ coordinates from CSV file.
