Hi Ankang, Thanks for this bug report. Can I ask what function you were using where this became a problem since it would be good to know what solvers or utilities were being effected by this bug. Cheers, Spencer. On 6 Apr 2016, at 07:14, Chris Cantwell <c.cantwell@imperial.ac.uk<mailto:c.cantwell@imperial.ac.uk>> wrote: Hi Ankang, Well-spotted and thank you for reporting it! I will apply the fix shortly which should then be included in our next patch release.

But this line makes a copy of "local", which hasn't been initialized yet. So this line should be substituted by "local = Array<OneD, NekDouble>(loc.num_elements(),loc.data());" Best regards, Ankang _______________________________________________ Nektar-users mailing list Nektar-users@imperial.ac.uk<mailto:Nektar-users@imperial.ac.uk> https://mailman.ic.ac.uk/mailman/listinfo/nektar-users -- Chris Cantwell Imperial College London South Kensington Campus London SW7 2AZ Email: c.cantwell@imperial.ac.uk<mailto:c.cantwell@imperial.ac.uk> www.imperial.ac.uk/people/c.cantwell<http://www.imperial.ac.uk/people/c.cantwell> _______________________________________________ Nektar-users mailing list Nektar-users@imperial.ac.uk https://mailman.ic.ac.uk/mailman/listinfo/nektar-users Spencer Sherwin McLaren Racing/Royal Academy of Engineering Research Chair, Professor of Computational Fluid Mechanics, Department of Aeronautics, Imperial College London South Kensington Campus London SW7 2AZ s.sherwin@imperial.ac.uk<mailto:s.sherwin@imperial.ac.uk> +44 (0) 20 759 45052
