Smooth Transition Inflation Option In ANSYS Meshing(Illustrated Expression)

Adjusting transition option according to the physical model in ANSYS Meshing is very important. You need to select the proper transition option for your FEA configuration. So we explained the whole Inflation Options in Mechanical Base. In this article we will explain the Smooth Transition option for Inflation Option in ANSYS Meshing.

How To Adjust Inflation Option To Smooth Transition In ANSYS Meshing?

To adjust Inflation Option in ANSYS Meshing as Smooth Transition, click on Mesh tab as shown by green arrow above then click on Inflation section as shown by red arrow. So you can select a Inflation Option as Smooth Transition inside the red box.

Smooth transition option calculates the local initial height of tetrehedral elements according to the total height of the elements, so the transition between each layer is smooth. The initial heaight will same for uniform mesh, but will be varying for non-uniform mesh.

Transition Ratio: This is the volume based growth rate of last tetrahedral elements. Works best in planar surfaces, if there is curvature, there can be inaccurracies in inflation layer.

Maximum Layers: This is the maximum layers number that will created on mesh structure. You can enter 1 to 1000 for it.

Growth Rate: The rate of thickness between adjacent layers starting from face that is Inflation Option is used.

Height of last prism mesh is equals to multiplacation of average edge length with transition ratio.So the height of the first layer is calculated with this formula;

Height of last prism = (heigth of first layer)* (Growth Rate ^ (Number of layers-1))

So you can easily make comments about increasing the growth rate means what for smooth transition.

These are very useful information to mesh your structure according to thes emathematical informatiıons in ANSYS Meshing.

The general logic for Smooth Transition in ANSYS Meshing is like that.
