Class 3 Error

If a vector magnitude variable, such as Velocity.trnmax, is used in CFX-Post, then behaviour unexpected to the user may result. This is because CFX-Post calculates Velocity.trnmax as the amplitude of the vector formed from the components Velocity u.trnmax, Velocity v.trnmax and Velocity w.trnmax and not the transient maximum of the amplitude of the Velocity vector at times throughout the simulation.

This is caused by a difficulty with the definition of these comple

The user can work around this difficulty by creating an Additional Variable equal to the amplitude of the vector variable required, and calculate transient statistics for that.

ANSYS CFX Release 12.0.1. The fix is a change to the documentation, which now describes the behaviour of the feature.
