Hello I started learning about the dual weighted residual error estimator. From what I read here: http://cadmus.usc.edu/UQ-SummerSchool-2013/bauman.pdf there are two approaches in libMesh: One, calculate the adjoint solution in an enriched space; two, use a classic error estimator for both the primal and the adjoint solutions. I have two questions with regards to this approach:
* What is the error incurred by choosing the second option? * In the case of elasticity, how do we apply the constitutive tensor? In both error estimators or just the primal? Basically, in the above presentation, slide 66, the application of R_k Thanks Miguel ------------------------------------------------------------------------------ _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
