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:

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. Controls with defaults that are affected by the Solver Preference setting include Element Order .

Other differences (such as what happens when you insert a Method control) are dependent on the behavior of the geometry bodies and the Rigid Body Behavior setting. See Rigid Body Meshing for more information.

Refer to Physics Preference for more information about defaults that are set based on Physics Preference and Solver Preference.
