Dear, deal.ii colleagues, A vector conversion problem has been troubled me for a long time.
It is the conversion between between dealii::PETScWrappers::MPI::Vector and a PETSc Vec. I have some functions written based on PETSc directly. So that I would like to use them directly in deal.ii. However, I need to convert vectors between dealii's MPI vectors to PETSc's generic vectors. Here is an simplified example: Vec a; // PETSc vector VecDuplicate(x, &a); // x is a dealii::PETScWrappers::MPI Vector generated previously VecCopy(x, a); dealii::PETScWrappers::MPI::Vector b(a); // dealii MPI vector I try to construct a dealii vector named with "b" based on PETSc Vector named "a". This should be OK in my opinion based on the constructor that is VectorBase <https://www.dealii.org/current/doxygen/deal.II/classPETScWrappers_1_1VectorBase.html#a08f6d7c4850e085271c225c5c19d7502> (const Vec &v) in the deal.ii's document: https://www.dealii.org/current/doxygen/deal.II/classPETScWrappers_1_1VectorBase.html#a08f6d7c4850e085271c225c5c19d7502 In addition, dealii::PETScWrappers::MPI::Vector is inherited from VectorBase, so the constructor VectorBase <https://www.dealii.org/current/doxygen/deal.II/classPETScWrappers_1_1VectorBase.html#a08f6d7c4850e085271c225c5c19d7502> (const Vec &v) should be able to be called by dealii::PETScWrappers::MPI::Vector as well. However, the error reported is: no matching function for call to dealii::PETScWrappers::MPI::Vector::Vector(_p_Vec*&) So may I get some information about this vector conversion problem? Thank you very much in advance! Zhidong Brian Zhang BTW, I found some info in the following forum but it is related to Mat conversion between deal.ii and PETSc: https://groups.google.com/forum/#!searchin/dealii/petscwrappers$3A$3Avector|sort:date/dealii/1HHsnUeJC28/qgBaE0SVBgAJ -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
