Dear deal.ii community, I am testing step-77 using the latest deal.ii release with sundials on (version 5.7.0). The example compiles and runs but not as expected, as I get the following output:
Mesh refinement step 0 Target_tolerance: 0.001 Computing residual vector... norm=0.231202 Computing Jacobian matrix Factorizing Jacobian matrix Solving linear system Computing residual vector... norm=0.231202 Computing residual vector... norm=0.402211 Computing residual vector... norm=0.627191 Computing residual vector... norm=0.857696 Computing residual vector... norm=1.08878 Computing residual vector... norm=1.31995 Computing residual vector... norm=1.55112 Computing residual vector... norm=1.78231 Computing residual vector... norm=2.0135 Computing residual vector... norm=2.24469 Computing residual vector... norm=2.47588 Computing residual vector... norm=2.70708 [KINSOL ERROR] KINSol The line search algorithm was unable to find an iterate sufficiently distinct from the current iterate. -------------------------------------------------------- An error occurred in line <518> of file </home/laura/Local/dealii/source/sundials/kinsol.cc> in function unsigned int dealii::SUNDIALS::KINSOL<VectorType>::solve(VectorType&) [with VectorType = dealii::Vector<double>] The violated condition was: status >= 0 Additional information: One of the SUNDIALS KINSOL internal functions returned a negative error code: -5. Please consult SUNDIALS manual. I wonder if this has something to do with my Sundials version or if anybody has a hint of what is happenning?
