Hi All,

I am using Nektar++ compressible flow solver. I noticed the p-adaptive algorithm can be used to optimize the computational cost. 

I have read the user guide but I still do not know how to perform it. I just add the AdaptiveModes and AdaptiveMinModes in the parameters. The SolverInfo like this:

         <SOLVERINFO>

            <I PROPERTY="EQTYPE" VALUE="EulerCFE" />

            <I PROPERTY="Projection" VALUE="DisContinuous" />

            <I PROPERTY="TimeIntegrationMethod" VALUE="ClassicalRungeKutta4" />

            <I PROPERTY="UpwindType"  VALUE="Roe"/>

            <I PROPERTY="Driver"                VALUE="Adaptive" />

        </SOLVERINFO>

I use FieldConver -m nummodes to see the polynomial order distributions. But it seems the polynomial order is not changed in the fields.

Does anyone familiar with it? I found a paper in 2013 about an inviscid transonic flow past a NACA0012 airfoil. I think this approach can be done by compressible flow solver.

Many thanks for your help!
