Great, glad we found the problem.

 

Just in case, we have several tutorials here (https://www.nektar.info/notebooks/) that might be helpful and save you times. Unfortunately, for some technical issues we cannot try them on web in Jupyter lab env but the explanations are detailed. I would look at this one in particular (https://www.nektar.info/notebooks//tutorials/basics-incns-solver/)

 

There are tutorials in other formats too (https://www.nektar.info/getting-started/tutorials/) which are basically different from the ones in notebooks.

 

Finally, in nektar++/solvers/IncNavierStokesSolver/Tests you can find many simple tests where sometimes could be helpful. Such tests are available for other solvers too

 

Eraadat,

Mohsen

Hi Syavash,

 

I assume you enclosed the filter in a filters tag as below, right?

If you have other filters, all goes inside <FILTERS> ….  </FILTERS> tags too. Eg. If you have FilterAeroforces too, all will looks like:

 

<FILTERS>

  <FILTER TYPE="ReynoldsStresses">
          <PARAM NAME="OutputFile">step95_4_averageField.fld</PARAM>
          <PARAM NAME="OutputFrequency">10</PARAM>
          <PARAM NAME="SampleFrequency"> 1 </PARAM>
  </FILTER>

 

<FILTER TYPE=”AeroForces”>

           <PARAM NAME=”OutputFile”>forces</PARAM>

          <PARAM NAME="OutputFrequency">10</PARAM>
          <PARAM NAME="SampleFrequency"> 1 </PARAM>
  </FILTER>

 

</FILTERS>

 

Hope this helps,

 

Cheers,

Mohsen

Dear All,

 

I have added the ReynoldsStresses filter to the main Nektar block in my session file:

 

  <FILTER TYPE="ReynoldsStresses">
          <PARAM NAME="OutputFile">step95_4_averageField.fld</PARAM>
          <PARAM NAME="OutputFrequency">10</PARAM>
          <PARAM NAME="SampleFrequency"> 1 </PARAM>
  </FILTER>

 

I am doing parallel simulations using 128 cores. 

However, I get no Reynolds stress fields in my directory. I don't get any errors or warnings either.

Am I missing something?

 

Kind regards
