It is difficult, if not impossible, to know what grid resolution is needed in all parts of a flowfield until you know what the flowfield is, which of course you do not know until you have a flow solution.


Mesh adaptation can automatically add finer mesh resolution in areas where it is needed by examining an error metric or flow gradients to determine where the existing mesh is not adequately resolving the flow.


Solution accuracy for an inlet was improved by an order of magnitude.
