3.3 Global Mesh Control

Global mesh controls are located in the Details View when the Mesh object is selected in the Tree
outline. Global settings are categorized into the following groups and are available through drop-
down menus:
a) Defaults Group
b) Sizing Group

c) Inflation Group
d) Assembly Meshing Group of Controls

e) Patch Conforming Options Group
f) Patch Independent Options
g) Advanced Group
h) Defeaturing Group

i) Statistics Group

3.3.1 Default Group

The Defaults group allows you to control these options:

Solver Preference: Solver Preference Choosing CFD as your Physics Preference causes a Solver
Preference option to appear in the Details View of the Mesh folder. The value of Solver Preference can
be CFX, Fluent, or Polyflow. Based on the value, the Meshing application sets certain defaults that will
result in a mesh that is more favorable to the CFX, Fluent, or Polyflow solver, respectively. Inflation
controls with defaults that are affected by the Solver Preference setting include:

w Aspect Ratio (Base/Height)
w Collision Avoidance
w Transition Ratio

Within the Mechanical application only, choosing Mechanical as your Physics Preference also causes a
Solver Preference option to appear, providing the analysis system is a Transient Structural or Rigid
Dynamics system during the initial geometry attach. In such cases, Solver Preference can be set to
either Mechanical APDL or Rigid Body Dynamics.
