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 ________________________________ From: nektar-users-bounces@imperial.ac.uk <nektar-users-bounces@imperial.ac.uk> on behalf of Siddarth Chintamani <siddarth.ch1990@gmail.com> Sent: 20 May 2016 21:42:28 To: nektar-users Subject: [Nektar-users] Seg fault with driver adaptive 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, Siddarth Chintamani
