Uniform Size Function In ANSYS® Meshing(Illustrated Expression)

It is very vital to optimize the mesh structure in FEA(Finite Element Analysis) of your physical or engineering system according to its geometry. Size function options can be made according to the geometric features in ANSYS® Meshing. These options are proximity size functioncurvature size function, and uniform size function. In this article we will explain about uniform size function;

  • How to adjust the size function option to uniform?
  • What is the uniform size function and where it needed to use in ANSYS® Meshing?

Uniform Size Function Option In ANSYS® Meshing

Adjust the Uniform Size Function in ANSYS® Meshing.

To adjust the size function to Uniform, click on the mesh tab then click on ‘Uniform’ as shown in the red box above in ANSYS® Meshing.

Uniform size function means, there is will no refinement on mesh on geometry based on geometric proximities or geometric curvatures. You simply specify minimum and maximum element size and the growth rate of the element sizes in ANSYS® Meshing.

Enter the required values for the Uniform size function in ANSYS® Mesher.

You need to enter the values below for Uniform Size Function in ANSYS® Mesher;

  • Min Size: Enter the minimum element size for the mesh structure.
  • Max Face Size: Enter the minimum element face size in the mesh structure.
  • Max Tet Size: Enter the maximum element size in the mesh structure.
  • Growth Rate: Enter a growth rate value from minimum element size and maximum element size. If you enter 1.5, the growth will be 50% percent in each layer.


This is the Uniform Size Function in ANSYS® Mesher.
