How do you control mesh size in Ansys?

The Global Mesh Size control allows you to control the global mesh sizing and properties. Click Refine Model > Mesh Control to open the Mesh Control tab. Click Global Mesh Size to open the Global Mesh Size dialog box. The global mesh size is controlled by the “Size Function” in the Ansys mesher.

How do I find my mesh Ansys details?

To view the mesh for the entire simulation:

  1. Right-click on the wireframe in the 3D Viewer and select Show surface mesh to display the mesh.
  2. Click the “Z” axis of triad in the viewer to get a side view of the object.

What is a good mesh quality Ansys?

A good rule of thumb is that the maximum skewness for tetrahedral cells should less be than 0.95. The maximum cell squish index for all types of cells should be less than 0.99. Cell size change and face warp are additional quality measure that could affect stability and accuracy.

How do I check my mesh quality in Ansys?

If you look under Mesh –> Statistics –> Mesh Metric you will find a drop down menu as shown in the image below. You can pick from a number of different metrics and ANSYS will provide the mesh statistics for the selected metric. I will only mention two of the most commonly used metrics – Skewness and Orthogonal Quality.

What is body sizing in Ansys meshing?

Body Sizing. The Body Sizing control also has the ability to use geometric bodies themselves to control the mesh refinement (in ANSYS Meshing terminology, these are termed a “body of influence”). A body of influence can be of any arbitrary shape/size and intersects the main fluid domain that we are trying to mesh.

How do I know if my mesh is good enough?

The most basic and accurate way to evaluate mesh quality is to refine the mesh until a critical result such as the maximum stress in a specific location converges: meaning that it doesn’t change significantly as the mesh is a refinement.

How do you know if mesh is good?

How do I know if my mesh is good enough?

  1. Software mesh control features (you can check the global mesh control in Ansys here)
  2. Mesh Metrics.
  3. Convergence Analysis.
  4. Test data or to theoretical values.
