The plane at which data is sampled is in the middle of the domain, so a periodic boundary is not suitable. Is this possible, and if so how can I do this? So far I have looked at using the "HistoryPoints" filter to extract data from the simulation along a plane, but I cannot quite figure out how to read the time dependent boundary data from file: 88 <BOUNDARYCONDITIONS> 95 <REGION REF="0"> 96 <D VAR="u" FILE="periodicInlet_<!--What do I put here??-->"/> 97 <D VAR="v" VALUE="0" /> 98 <D VAR="w" VALUE="0" /> 99 <N VAR="p" USERDEFINEDTYPE="H" VALUE="0" /> 100 </REGION> ... 185 </BOUNDARYCONDITIONS> ... 256 <FILTER TYPE="HistoryPoints"> 257 <PARAM NAME="OutputFile">periodicInlet</PARAM> 258 <PARAM NAME="OutputFrequency">1</PARAM> 259 <PARAM NAME="OutputOneFile">false</PARAM> 260 <PARAM NAME="plane"> 261 100, 100, 262 0, 0, 0, 263 0, 7, 0, 264 0, 0, 2, 265 0, 7, 2 266 </PARAM> 267 </FILTER> When using <PARAM NAME="OutputOneFile">false</PARAM>, the history point data is saved in files based on index (e.g. periodicInlet_0, periodicInlet_1, periodicInlet_2, etc.) Any suggestions are appreciated.
