Re: [deal.II] Install scalapack and mumps fail with MPI fortran error

I ran into the wrong direction then... There are some trilinos warning on my vm machine but deal.ii install was success so I skip over them. Locating the error is very helpful. Thank you Wolfgang! Best, Wayne 在2023年2月21日星期二 UTC+8 11:38:27 写道: > > > Thank you Wolfgang. I shift from mumps

Thank you Wolfgang. I shift from mumps to superlu_dist. The trilinos is compiled with superlu_dist completely, but another error shows up. It says: * Compiler setup check for DEAL_II_HAVE_USABLE_FLAGS_DEBUG failed with: * Change Dir:

Re: [deal.II] How to apply Spherical Manifold

Thank you very much sir for your explanation. I have assigned material id to different domains. Now I am trying to set spherical manifold id by using the following code for (const auto : tri.cell_iterators()) { double v = (cell->center()[0])*(cell->center()[1]) ; if

Hi Lilanath, If you check step-50 https://www.dealii.org/developer/doxygen/deal.II/step_49.html#Importingfromexternalprograms you can see an example where it works correctly (including the .geo file https://github.com/dealii/dealii/blob/master/examples/step-49/example.geo ) Maybe this is

Re: [deal.II] B-spline basis functions to interpolate nodal values (control points) in 1d

2023-02-20 Thread Luca Heltai
Simon, If you are willing to do some work, Bernstein basis functions are implemented in deal.II (which are B-spline basis with C0 continuity). You could exploit BezierExtractor https://onlinelibrary.wiley.com/doi/full/10.1002/nme.2968 and use the facilities of deal.II to work with cubic

Re: [deal.II] How to apply Spherical Manifold

2023-02-20 Thread Luca Heltai
At the moment, you are setting the manifold ID on the boundary of your *domain* with the call to tri.set_all_manifold_ids_on_bounary(4); tri.set_manifold (4, manifold_neg); And then you are telling the triangulation to use on it the SphericalManifold<2> manifold_neg(center). Then you re-do
