Meshing Instructions for Hip Model

  1. Importing Geometry:

    • Open SimModeler
    • If the file is in parasolid format, go to File → Import Geometry. For files in .obj or .stl format, choose Import Discrete Data.
  2. Preparing for meshing:

    • Navigate to the Modeling tab, choose Delete Parts, and select the screws.
    • In the Meshing tab, click on Generate Mesh. Uncheck “Structured Mesh” and proceed. Upon successful generation, view the mesh by selecting Show Mesh, which creates an .sms file. (Remember to return to the .smd file for generating a new mesh if required.)
  3. Refining Mesh:

    • Use Mesh Attributes located on the right-hand side of the screen.
    • The following chart represents some suggested Mesh Attributes and corresponding values:
      TypeSub-TypeValue
      Mesh SizeAbsolute0.001
      Mesh Curvature RefinementAbsolute0.005
      Volume Shape MetricAspect Ratio3.0
      Allow Refinement For ShapeRelative0.0001
    • After making refinements, regenerate the mesh to incorporate the changes.
  4. Quality Check:

    • Assess the quality of the mesh by going to the .sms file and navigating to the Display Tab.
    • Click Mesh Stats and scrutinize the Aspect Ratio.
  5. Exporting Mesh:

    • To export the mesh, navigate to File > Export Mesh.
    • Save the file if not done previously.
    • Choose the export format as Abaqus 3D (.inp).
  6. Meshing Screws Separately:

    • Follow the same steps as for the bone meshing process for the screws.
