Hi all, I'm trying to use the Reynolds Stresses time - averaged filter and the History Points filter on my current case. The appropriate section of the .xml file looks like this <FILTER TYPE="ReynoldsStresses"> <PARAM NAME="OutputFile">AverageField</PARAM> <PARAM NAME="RestartFile">MyRestartAvg.fld</PARAM> <PARAM NAME="OutputFrequency">100</PARAM> <PARAM NAME="SampleFrequency"> 10 </PARAM> </FILTER> <FILTER TYPE="HistoryPoints"> <PARAM NAME="OutputFile">TimeValues</PARAM> <PARAM NAME="OutputFrequency">10</PARAM> <PARAM NAME="Points"> 1 0 10 2 0 10 3 0 10 4 0 10 5 0 10 6 0 10 7 0 10 </PARAM> </FILTER> The simulation runs fine over 10000 time steps. However, no .his files or .fld files for reynolds stresses are generated. I'm in a bit of a quandry as to how to resolve this issue. PFA the full .xml file as well. -- *Amitvikram Dutta* Graduate Research Assistant Fluid Mechanics Research Lab Multi-Physics Interaction Lab University of Waterloo
