Precedence Rules for Mesh Controls
When you apply the Maximum Element Size and Minimum Element Size mesh controls to the model, Creo Simulate uses following precedence rules while creating a FEM mesh:
Precedence of references — When you apply the same type of mesh control to different references in the model, Creo Simulate uses following precedence rules:
Situation
Rule
You apply the same type of mesh control to a surface and a quilt. The surface is a member of the quilt.
The mesh control applied to the surface takes precedence.
You apply the same type of mesh control to a part boundary and a surface of the part.
The mesh control applied to the surface takes precedence.
You apply the same type of mesh control to a component and a surface of the component.
The mesh control applied to the surface takes precedence.
You apply the same type of mesh control to a volume and a surface in the volume.
The mesh control applied to the surface takes precedence.
You apply the same type of mesh control to a component and a quilt surface of the component.
The mesh control applied to the quilt surface takes precedence.
You apply the same type of mesh control to a component and a part boundary that lies within the component.
The mesh control applied to the part boundary takes precedence.
You apply the same type of mesh control to a part boundary and a volume region in the part.
The mesh control applied to the part boundary takes precedence.
You apply the same type of mesh control to a component and a volume region in the component.
The mesh control applied to the volume region takes precedence.
You apply the same type of mesh control to two different volume regions overlapping each other.
When Creo Simulate generates mesh for the overlapping region, the mesh control applied to the most recent volume region takes precedence.
Precedence of mesh controls — When you apply the Maximum Element Size and Minimum Element Size mesh controls to a same reference in the model, Creo Simulate uses the following precedence rules:
If the element size for the Maximum Element Size mesh control is smaller than the element size for Minimum Element Size mesh control, the Maximum Element Size mesh control takes precedence. Creo Simulate displays a warning message while generating the mesh.
If the element size for the Maximum Element Size mesh control is larger than the element size for Minimum Element Size mesh control, the Maximum Element Size mesh control takes precedence without a warning message.
A mesh control applied to a higher level component takes precedence over a mesh control applied to a lower level component. For example, you have applied a Maximum Element Size mesh control to an assembly. The maximum element size is 20 cm for the assembly. Similarly you have applied another Maximum Element Size mesh control to a part in the assembly. The maximum element size is 10 cm for the part. When you generate the FEM mesh, the maximum element size on the part is 20 cm. Creo Simulate ignores the mesh control applied to the part.
