A new Flow front speed result has been created for 
Dual Domain and 
Midplane meshed models, and replaces the existing Flow front speed at center result.
The new Flow front speed result is a bulk, or average, result and is based on gradient of fill time instead of gradient of pressure. This result addresses the sometimes spotty appearance of the Flow front speed at center, as illustrated in the figure below, where (A) is the old Flow front speed at center result, and (B) is the new Flow front speed result.
Comparison between the old Flow front speed at center result and the new Flow front speed result
Note: A Flow front speed at center result created from an older software release and imported as part of a .sdy file, can still be viewed, but new Flow front speed at center results can no longer be created.
