The option is available in the Type field if you selected a body and Use Adaptive Sizing is set to No. Using this option, you can set one body as a source of another body (that is, a ). The will influence the mesh density of the body that it is scoped to, but it will not be a part of the model geometry nor will it be meshed. bodies are noted in the Details View of each prototype.
Although the Behavior option is not available for , behaves as a Soft setting. That is, in the vicinity of a , the specified sizing must be larger than the smallest Curvature Min Size/Proximity Min Size and smaller than the global Max Size to have an effect on the mesh size distribution. The specified sizing imposes a local maximum size on all elements that are inside the boundary of the body. This is in contrast to the option, which behaves as a Hard setting.
Remember the following notes when using :
-
If your source body is a sphere, it is best for you to use the option instead of . is intended for non-spherical bodies.
-
In general, users are discouraged from defining a and a such that the regions of influence overlap. In cases where elements fall within overlapping bodies/spheres of influence, elements will be created using the sizing that appears lowest in the Tree.
-
You cannot apply loads, mesh controls, etc. on bodies of influence. Bodies of influence are used only to influence the sizing controls and therefore only sizing attributes can be applied to them.
-
You can suppress and unsuppress bodies of influence.
-
If you are using with Match Control, be aware that the body of influence will not be copied from one matched entity to the other. As a workaround, you can copy the body in the DesignModeler application and use both bodies as your source.
-
When using Assembly Meshing, the body of influence cannot be scoped to a line body. If you want to use a body of influence with a virtual body, you can scope the body of influence to any body in the geometry. The body of influence does not have to be inside or even in contact with the scoped body. Although Contact Sizing is supported for assembly meshing algorithms, if it is applied to entities on a body that is scoped to a body of influence, the contact sizing is ignored.
In this tutorial, you will learn to use the Body of Influence tool using Ansys Meshing. With this tool you can generate localized mesh.
Ansys Meshing – Keyframe Animation
You can make animations based on keyframes. Keyframes define the start and endpoints of each section of animation.
Ansys Meshing – Match Control
In this tutorial, you will learn how to use the Match Control tool in Ansys Meshing. Match Control allows duplicating the mesh in a body. We have two option Match Control Cyclic and Arbitrary.

Ansys Meshing – Mesh Copy Control
The Mesh Copy control enables you copy mesh from one body to another. This option can be used to reduce the mesh setup time for repetitive bodies/parts. Association to CAD is maintained after performing mesh copy.
Mesh controls are scoped only to the source anchor body. When the mesh is generated, the source anchor body is meshed and the mesh is then copied to targets.
