Unfotunately, this filter is never activated. The system is set-up to solve for 100 time steps and I wish to record values at points as well as lines. To start with, I played around with the points filter setup and this the format which I have used: <FILTERS> <FILTER TYPE="HistoryPoints"> <PARAM NAME="OutputFrequency">1</PARAM> <PARAM NAME="Points"> -100 0 0 </PARAM> </FILTER> <FILTER TYPE="Checkpoint"> <PARAM NAME="OutputFile">IntermediateFields</PARAM> <PARAM NAME="OutputFrequency">1</PARAM> </FILTER> </FILTERS> For some reason, the .his files are never written but .chk files are. What could I be doing wrong in my setup ? Regards, Ishan
Hi Ishan, You forgot to give a file name for history points, syntax is the same as you did for the checkpoint filter Cheers Mohsen Dr Mohsen Lahooti, PhD Lecturer in Fluid-Structure Interaction Mechanical Engineering Newcastle University School of Engineering Room 4.28, Stephenson Building Claremont road Newcastle upon Tyne NE1 7RU UK Email mohsen.lahooti@newcastle.ac.uk Webpage<https://www.ncl.ac.uk/engineering/staff/profile/mohsenlahooti.html> ________________________________ From: nektar-users-bounces@imperial.ac.uk <nektar-users-bounces@imperial.ac.uk> on behalf of Nande, Ishan A. <ian9@leicester.ac.uk> Sent: Thursday, March 7, 2024 4:27:46 PM To: nektar-users <nektar-users@imperial.ac.uk> Subject: [Nektar-users] Filters in Acoustic Solver ⚠ External sender.

Hello Mohsen, It still doesn’t get activated.

Hello again, I was able to make the setup work but by providing the HistoryPoints setup as a separate XML file and then supplying this file separately on the command line to the solver. As Mohsen pointed it out in a short call with me, the issue is probably with the XML syntax. Thanks Mohsen for the inputs.
