Dear PDELab Members,<br><br>I am a new dune user. I am also not so experienced in C++, so still learning both.<br>I have used the example DG code in pdelab/localoperator/convectiondiffusiondg.hh<br>to solve a scalar nonlinear reaction-diffusion equation and it worked well.<br>
I have extended the code to solve a two component nonlinear reaction-diffusion<br>system. However, at run time I get the error below:<br><br><i>Dune reported error: NewtonLinearSolverError [linearSolve:/homes/okiro/DUNE/dune-svn/dune-pdelab/dune/pdelab/backend/../newton/newton.hh:174]:<br>
NewtonSolver::linearSolve(): Linear solver did not converge in 0 iterations.</i><br><br>I suspect the error is in my local operator (especially in alpha_skeleton()). I would be grateful<br>if someone could assist me resolve this error. I can provide the local operator if possible.<br>
Thank you.<br><br>Kind regards,<br clear="all"><br>-- <br><div>Jared Ouma Okiro,</div>
