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.

 

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

Hello,

 

I am trying to set-up a “HistoryPoints” filter in the AcousticSolver which is solving Linearized Euler Equations.

 

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
