[Libmesh-users] How to make use of Libmesh in my project

Dear Libmesh team, I'm a beginner in computational science and c++ programming. So please excuse If I am not making any sense at somewhere. I am trying to develop a structural mechanics solver for non-linear analysis problems. I don't have previous C++ experience and haven't used any C++ FEA Libr

[Libmesh-users] Looping over all "coupled" elements

Roy, This question is probably for you. I'm curious if we've gained or could potentially gain a method for looping over all "coupled" elements (if this is the right terminology). Let me try to clarify what I mean since we've used the wrong terminology for so long and I'm probably still using it in

[Libmesh-users] incorporate field parameters in libMesh

Hi all, I'm a new user of libMesh. I am trying to incorporate patient-specific MRI data with a finite element model. For this purpose, I want to define a field map with nodal values assigned based on the images. The field then needs to be integrated to assemble the stiffness matrix. I've noticed

Re: [Libmesh-users] Recycling preconditioned in system_of_equations7.C

LinearSolver does not have the capability to have null spaces attached to it. In my opinion, wouldn’t it be a good idea to have a Solver class from which all the solvers can inherit common things like attaching null spaces or setting up the preconditioner? On 11/16/16, 8:50 AM, "Salazar De Troya,

Re: [Libmesh-users] Recycling preconditioned in system_of_equations7.C

A slight tangent but still related to this topic of reusing the preconditioner: The TimeSolver in DifferentiableSystem has both a DiffSolver and a LinearSolver. The DiffSolver is used in the regular primal/forward solve() and the LinearSolver in the adjoint_solve(). It would be convenient to reus
