GiD user manual : Generating the mesh with assignment of size around points

  • Choose View->Rotate->Plane XY (Original) . This way we will have a side view, and View->Mode->Geometry and Render->Normal to see the geometry like the image

Side view of the part.

  • Choose Mesh->Unstructured->Assign sizes on points . A window appears in which to enter the element size around the point to be selected. Enter 0.7 and click Assign .
  • Select only the points on the wheel profile (see next figure). One way of doing this is to select the entire part and then deselect the points that form the prism hole. Press ESC to conclude the selection process.
  • The window appears again, click Close to finish.

The selected points of the wheel profile

  • Choose Mesh->Generate mesh .
  • A window opens asking if the previous mesh should be eliminated. Click Yes . Another window appears in which the desired element size should be entered. Leave the previous value of 10 unaltered.




  • A third window shows the meshing process. Once it has finished, click View mesh to visualize the resulting mesh.
