Meshing is a very tough and very important thing in finite element analyses especially done in ANSYS®. In this article, you can find out lots of information about ANSYS® meshing, to obtain the required mesh structure for your engineering system.
Most Important Mesh Options In ANSYS® Mesher
Here the list of the most important mesh options in ANSYS® Mesher;
- Relevance Option In ANSYS® Meshing: The relevance option of meshing in ANSYS® is the most basic way to increase the number of mesh nodes and elements on your geometries. With the increasing relevance, mesh density is also increased in ANSYS® Mesher.
- Smoothing Options For Mesh In ANSYS®: SSmoothing options is a very important option to optimize element quality in ANSYS® Meshing. You can adjust the smoothing quality of your mesh as low, medium, and high.
- Mesh Metrics In ANSYS® Meshing: Mesh metrics is a very important tool to see the various situations of your mesh structure such as element quality, warping factor, jacobian ratio, and others. You can do assessments about the obtained mesh structure, and you can de required updates on your mesh structure in ANSYS®.
- Changing The Sizes Of Mesh Elements In ANSYS®: To obtain better mesh structures or detailed mesh structures, you can optimize your sizes of elements of mesh structure according to your computational power. Smaller elements sizes mean finer mesh structures in ANSYS® Meshing.
- Shape Checking Options In ANSYS® Meshing: Selection of a proper shape checking option is also a very important thing in ANSYS® Meshing. In shape checking options, you can find; Standard Mechanical, Aggressive Mechanical, Nonlinear Mechanical, Electromagnetics, CFD, and Explicit. According to your analysis type in ANSYS®, select the proper shape checking option.
- Option About Element Midside Nodes In ANSYS® Meshing: You can add extra element nodes into the mid side of the element sides with this option. You select ‘Kept’ and ‘Dropped’ in ANSYS® Meshing.
- Size Function Options In ANSYS® Meshing: You need to define the size function option according to the shape of your part or parts for mesh structure in ANSYS® Mechanical. You can select the size function option as Curvature, Proximity, and Uniform.
- Automatic Mesh Based Defeaturing Option: This is an option about the defeaturing the mesh structures on dirty geometries.
- Initial Size Seed Option: You can select one of the initial seeding according to the determination of meshing priority of assemblies in ANSYS® Mesher.
- Mesh Transition In ANSYS® Mesher: The growth rate between the different mesh structures in ANSYS® Mesher is defined with the transition option available in ANSYS®.
- Span Angle Center Option: In this option of ANSYS® Mesher, the mesh structure of the curvature regions of your geometry will be finer. Three options are available: Coarse, Medium, and Fine.
- ANSYS® Meshing Inflation Options: You can create mesh structures by entering various values for various options in meshing inflation options. As you understand from its name that, you are adjusting the inflation of size of mesh layers starting from a surface. There are a bunch of options that you can adjust mesh inflation in ANSYS®: Total Thickness, First Layer Thickness, Smooth Transition, First Aspect Ratio, Last Aspect Ratio.
- Creating Tetrahedron Element Shaped Mesh Structure: The element shape of mesh structure is also a very important parameter in ANSYS® Meshing. For some geometric shapes, tetrahedron elements can be more appropriate.
- Creating Hexagonal Elements In ANSYS® Meshing: You can create your mesh structure in a strict hexagonal shape. More even mesh structures can be obtained with this element shape in ANSYS®.
- Showing Mappable Bodies In ANSYS®: If you need to do mesh mapping in ANSYS® Mesher, you can use this option to see mappable bodies at your assembly or geometries in ANSYS® Mechanical.
- Exporting Mesh Structures From ANSYS® Mesher: Also you can export the mesh structure that you created in ANSYS® mesher to other sources as .stl format.
These are the general options and tools to create your mesh structure in ANSYS® Mechanical or mesher easily. Obtaining an optimized mesh structure is very important in terms of;
- The shape of your geometries,
- Type of analysis that you are carrying on in ANSYS®,
- Your computational properties to creating and solving analyses.
