No, when you have a function you want to transfer you distribute() with the old constraints first, then transfer it with SolutionTransfer. Afterwards you don't need to apply the new constraints as the transfer should have done it correctly already. At least I think it should be. :-) Can you output the Eigenvectors and look at them to find out if constraints are the problem? -- Timo Heister http://num.math.uni-goettingen.de/~heister _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
