Re: [Nektar-users] Seg fault with driver adaptive

22 May 2016

      Hi Siddarth,

That is strange. I tried with the session file you sent me and it worked for me (the fix for the scalar transport is not in this branch yet, but that is a different problem).

The function in ExpList should not be called, since it is overridden in DiscontField2D. Could you provide some more information on your nektar++ installation (os, compiler, etc...)?

Cheers,
Douglas

Hi douglas,

I tried the branch feature/ExtrapolateRefractoring. But the code fails at:

        void ExpList::v_GetBndElmtExpansion(int i,
                            boost::shared_ptr<ExpList> &result,
                            const bool DeclareCoeffPhysArrays)
        {
            ASSERTL0(false,
                     "This method is not defined or valid for this class type");
        }

which is being called by:

                    m_fields[0]->GetBndElmtExpansion(n, BndElmtExp, false);

inside the function void Extrapolate::GenerateHOPBCMap() in solvers/IncNavierStokesSolver/EquationSystems/Extrapolate.cpp

Thank you,
Siddarth

Hi Siddarth,

I believe this is being caused by the outflow boundary conditions using some static variables.

This should be fixed in the branch feature/ExtrapolateRefactoring, so you might want to try that.

Cheers,

Douglas

Hi Siddarth,

The test IncNavierStokesSolver/Tests/KovaFlow_3DH1D_adaptive_16modes_FFTW_Mapping.xml uses the adaptive driver.

Also, if you could send your session file I can check to see if I figure out what is happening.

Cheers,

Douglas

Hello all,

I am tyring to run the IncNavierStokesSolver with adaptive polynomial order. My simulation fails with seg fault as soon as it restarts with adapted polynomial orders. I might be setting my input file wrong. It would be really helpful if someone could point me to an example with adaptive polynomial order.

Thank you,
