I need to apply a laplace_transformation to a huge 3D mesh. It works fine for a limited number of cells, but when the number increases I got the message:
DEAL:cg::Failure step 1000 value 0.00155975 terminate called after throwing an instance of 'dealii::SolverControl::NoConvergence' what(): Iterative method reported convergence failure in step 1000 with residual 0.00155975 make: *** [run] Aborted I have modified the hard-wired SolverControl parameter n from 1000 to 10000 in grid_generator.cc and now it seems to work. It there a more "clean" way to do this? Thanks, Luca _______________________________________________
