Hi Chengeng,

Did you set up the number of adaptive iterations that you want to perform?

For example, if you want to run 2000 time steps in total and adapt the mesh every 500 time steps, so three times, you might set it up as:

        <PARAMETERS>

            <P> NumSteps              = 500                           </P>

            <P> NumRuns               = 4                             </P>

        </PARAMETERS>


Cheers,

Margarida

Hi everyone,
I would like to test the efficiency of p-adaptive method in CompressibleFlowSolver. But I could not find any sample which shows me how to modify the session file. I have tried the same set up found in incompressible solver Tests, as follows,

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

<PARAMETERS>
    <P> AdaptiveMaxModes = 7               </P>
    <P> AdaptiveMinModes = 4               </P>
</PARAMETERS>

The CompressibleFlowSolver ran successfully (simulated forward step problem). But I didn't find any difference between the results of "Adaptive Driver" and "Standard Driver". 

Any suggestions are appreciated. 

Regrads,
Chengeng
