Re: [deal.II] Supported matrix/vector to LinearOperator

Thanks, Bruno and Jean-Paul. I will not use the TrilinosWrapper::SolverDirect in inverse_operator, replaced by an iterative solver. But Bruno, this example initializes a precondition by a matrix preconditioner.initialize(system_matrix, data); While I can't get the entity of the matrix, I want

Dear Wolfgang, Thank you for the hints. The second approach seems easy to start with. One follow-up question: The mesh (which is initially periodic at the boundaries) is refined adaptively during the simulation and it cannot be guaranteed if both the left and the right boundary faces would be

[deal.II] Python bindings

Hello everyone, I'd like to write some custom Python bindings for deal.ii, and as a first step, I've been trying to reproduce the ipython notebook for step-49. I've built deal.ii version 9.3.0 with the -DDEAL_II_COMPONENT_PYTHON_BINDING=ON configuration, yet when I run the notebook, the

Re: [deal.II] Supported matrix/vector to LinearOperator

Dear Chen, Bruno pointed you to the exact example that I was going to. It is certainly possible to use linear operators as preconditioners for solvers. It looks like support for TrilinosWrappers::SolverDirect has not yet been implemented:

Re: [deal.II] Supported matrix/vector to LinearOperator

Chen, I am not sure if TrilinosWrappers::SolverDirect is supported but for your second point, you can use the linear_operator as a preconditioner. That's exactly what's done here for example. The

Re: [deal.II] Supported matrix/vector to LinearOperator

Hi everyone, More questions: 1. where can I find the supported linear solver of Trilinos of linear_operator? TrilinosWrappers::SolverDirect seems not to be supported by the linear_operator 2. Does linear_operator can be a preconditioner? for example, SparseMatrix A, B, C, D, E, F; Matrix
