Free Meshing
• ANSYS has a free meshing routine and its easy to use
• Will it give good results when compared with mapped meshing?
Free Meshing• Create the Geometry
• Define the Mesh Size>Preprocessor
>Meshing>Size Controls>Manual Size>Global>Size
Free Meshing• Create the Geometry
• Define Mesh Size>Preprocessor
>Meshing>Size Controls>Smart Size>Basic
Free Meshing• Create the Geometry
• Define Mesh Size
• Free Mesh>Meshing>Mesh>Areas>Free>Select the Area to Mesh
Free Meshing
• Good- -easy to create the geometry -meshing is fast
• Bad- -some triangular elements are used-some elements may have poor aspect ratios
Mapped Meshing• Create the Geometry
-create the geometry in smaller sub areas using key points and lines
Mapped Meshing• Create the Geometry• Concatenate Lines
-sub areas must be bounded by 3 or 4 lines-concatenate lines around areas until each sub area has no more than 4 boundary lines
Mapped Meshing• Create the Geometry• Concatenate Lines• Mesh each area
separatelyMeshing>Mesh>Areas>Mapped>3 or 4 sided
Mapped Meshing• Create the Geometry• Concatenate Lines• Mesh each area
separately• Optional: Check Mesh
-Meshing>Check Mesh>Individual Elm>Plot Warning/Error Elements
