Thanks Mohsen, This is very helpful. I found out the learning materials are not unified and as you pointed out it took me a while to setup my own case. I will certainly have a look at those you introduced. Kind regards syavash On Wed, Apr 5, 2023, 00:48 Mohsen Lahooti <Mohsen.Lahooti@newcastle.ac.uk> wrote:
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/ <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 Mohsen, mokhlesam!
Thank you for your kind help. That is what I missed!
Kind regards

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
