Re: [deal.II] install problems with clang@12.0.0 and Xcode12.0 from spack

I notice that you are using cmake from /opt/local/bin, but spack would have installed its own cmake. Could you try using cmake from spack to compile and then run the example ? best praveen > On 29-Sep-2020, at 7:35 PM, 'Alexander Greiner' via deal.II User Group > wrote: > > Hi Luca, > > I ra

Re: [deal.II] Re: Initialization of PETSc::MPI::BlockSparseMatrix

Gabriel, 1. Regarding the initialization of PETSc::MPI::BlockSparseMatrix: I have used the the IndexSet::split_by_block() function and this indeed works good. Thanks for the suggestion! Unfortunately, I have encountered another issue. The PETSc::MPI::BlockSparseMatrix must be partitioned

[deal.II] Classical returning mapping algorithm for plasticity in deal.ii

Dear fellow community members, Hi! I want to simulate some simulation cases based upon the elastoplastic material model. They involve the loading and then unloading of the material too. I tried with the step-42 but apparently it is for

Dear Alex, what happens after loading dealii with `spack load dealii`, if you try to build (from scratch) `step-40`? Can you send us the output of cmake and make? Luca. On Mon, Sep 28, 2020 at 4:46 PM 'Alexander Greiner' via deal.II User Group < dealii@googlegroups.com> wrote: > Hi Luca, > >

Re: [deal.II] Eigenvalues and Eigenvectors of BlockSparse Matrix

Hi Bruno and Jean, Thanks a lot for your help with the eigenvalue problem. I am able to solve the standard eigenvalue problem, and have tested my code on simple problems. The results are matching (compared them with the MATLAB eigenvalue analysis). Thanks again! Animesh On Tuesday, September
