SYMPTOM:
The specified Start Iteration List for transient statistics objects only appears to be honoured by the CFX Solver for the first variable in the list.
PROBLEM:
If a transient statistics object is requested and contains multiple variables, and the Start/Stop Iteration List contains fewer integers than variables, then all subsequent variables in the list will start collecting statistics at Timestep 1. Although this is by design (and is documented), a change in the behaviour for Release 10.0 SP1 has been made to make it more intuitive. The new behaviour is such that subsequent variables in the list will start collecting statistics at the last specified timestep in the Start Iteration List.
For example, suppose a transient statistics object contains Pressure and Velocity in the variables list, and the `Start Iteration List' was set to 500 as follows:
TRANSIENT STATISTICS: Transient Statistics 1
Option = Arithmetic Average
Output Variables List = Pressure, Velocity
Start Iteration List = 500
END
In Release 10.0 statistical calculations for Velocity would start at Timestep 1. In Release 10.0 SP1, they will start at Timestep 500.

WORKAROUND: Specify individual Start/Stop Iterations for each variable in thelist. FIXED IN: Release 10.0 SP1. |
