Hi You can add a FIlter in your session file. Suppose you want to record the solution at x = (1.75, 0.075, 0) add the following filters in your FILTERS block of Session file. <FILTER TYPE="HistoryPoints"> <PARAM NAME="HistoryOut">TimeValues</PARAM> <PARAM NAME="OutputFrequency">10</PARAM> <PARAM NAME="Points"> 1.75 0.075 0 2.0 0 0 3.0 0.15 0 4.0 0 0 5.5 0.3 0 6.0 0 0 </PARAM> </FILTER> Hope this helps.

Hi, Could some please give me some hints as how to output time series data (for example, pressure evolution at some given point) using Nektar++?

Thanks
