Dear all,

Is there any way to make isocontour module work in filter mode for derived quantities, e.g., Q field?

I tried the following in config.xml file for a run using IncNavierStokesSolver solver:

     <FILTER TYPE="FieldConvert">
       <PARAM NAME="OutputFile">Q_214.fld</PARAM>
       <PARAM NAME="OutputFrequency">10</PARAM>
       <PARAM NAME="Modules"> QCriterion </PARAM>
     </FILTER>

     <FILTER TYPE="FieldConvert">
       <PARAM NAME="OutputFile">Q_214_iso2000.fld</PARAM>
       <PARAM NAME="OutputFrequency">10</PARAM>
       <PARAM NAME="Modules"> isocontour </PARAM>
       <PARAM NAME="fieldstr"> Q </PARAM>
       <PARAM NAME="fieldvalue"> 1000 </PARAM>
     </FILTER>

The first filter works, and writes out the 3D Q field. However, second one does not work as Q is not defined as a field in the solver.

Is there any possibility to address this other than extending the related solver to contain the calculation of the field?

Thanks,
