Hi all,

I'm running an SVV LES simulation using the IncNavierStokesSolver. Ran the initialisation bit and finally started collecting the statistics using the filter below:

         <FILTER TYPE="ReynoldsStresses">
             <PARAM NAME="OutputFile">AverageField_0pt1sOnwards</PARAM>
             <PARAM NAME="OutputFrequency">1000</PARAM>
             <PARAM NAME="SampleFrequency">1</PARAM>
         </FILTER>

Checked the <uu> component on a sliced plane and it looked fine (top figure in the attachment). However, when I resume the simulation using the last written Average Field and the chk file as a starting point, the <uu> (and the other components) looks a bit corrupted (bottom figure in the attachment).

         <FILTER TYPE="ReynoldsStresses">
             <PARAM NAME="OutputFile">AverageField_0pt5sOnwards</PARAM>
             <PARAM NAME="RestartFile">AverageField_0pt1sOnwards_stress.fld</PARAM>
             <PARAM NAME="OutputFrequency">1000</PARAM>
             <PARAM NAME="SampleFrequency">1</PARAM>
         </FILTER>

May be I'm missing something! Has anyone encountered this before? If yes, is there a workaround?

PS. Average velocities <U> look similar in the two cases.

BR,

Vishal
